Airflow 2.0.0
The experimental REST API is disabled by default
The experimental REST API is disabled by default. To restore these APIs while migrating to
the stable REST API, set enable_experimental_api
option in [api]
section to True
.
Please note that the experimental REST API do not have access control. The authenticated user has full access.
SparkJDBCHook default connection
For SparkJDBCHook default connection was spark-default
, and for SparkSubmitHook it was
spark_default
. Both hooks now use the spark_default
which is a common pattern for the connection
names used across all providers.
Changes to output argument in commands
From Airflow 2.0, We are replacing tabulate with rich to render commands output. Due to this change, the --output
argument
will no longer accept formats of tabulate tables. Instead, it now accepts:
table
- will render the output in predefined tablejson
- will render the output as a jsonyaml
- will render the output as yaml
By doing this we increased consistency and gave users possibility to manipulate the output programmatically (when using json or yaml).
Affected commands:
airflow dags list
airflow dags report
airflow dags list-runs
airflow dags list-jobs
airflow connections list
airflow connections get
airflow pools list
airflow pools get
airflow pools set
airflow pools delete
airflow pools import
airflow pools export
airflow role list
airflow providers list
airflow providers get
airflow providers hooks
airflow tasks states-for-dag-run
airflow users list
airflow variables list
Azure Wasb Hook does not work together with Snowflake hook
The WasbHook in Apache Airflow use a legacy version of Azure library. While the conflict is not
significant for most of the Azure hooks, it is a problem for Wasb Hook because the blob
folders
for both libraries overlap. Installing both Snowflake and Azure extra will result in non-importable
WasbHook.
Rename all
to devel_all
extra
The all
extras were reduced to include only user-facing dependencies. This means
that this extra does not contain development dependencies. If you were relying on
all
extra then you should use now devel_all
or figure out if you need development
extras at all.
Context variables prev_execution_date_success
and prev_execution_date_success
are now pendulum.DateTime
Rename policy to task_policy
Because Airflow introduced DAG level policy (dag_policy
) we decided to rename existing policy
function to task_policy
to make the distinction more profound and avoid any confusion.
Users using cluster policy need to rename their policy
functions in airflow_local_settings.py
to task_policy
.
Default value for [celery] operation_timeout
has changed to 1.0
From Airflow 2, by default Airflow will retry 3 times to publish task to Celery broker. This is controlled by
[celery] task_publish_max_retries
. Because of this we can now have a lower Operation timeout that raises
AirflowTaskTimeout
. This generally occurs during network blips or intermittent DNS issues.
Adding Operators and Sensors via plugins is no longer supported
Operators and Sensors should no longer be registered or imported via Airflow's plugin mechanism -- these types of classes are just treated as plain python classes by Airflow, so there is no need to register them with Airflow.
If you previously had a plugins/my_plugin.py
and you used it like this in a DAG:
from airflow.operators.my_plugin import MyOperator
You should instead import it as:
from my_plugin import MyOperator
The name under airflow.operators.
was the plugin name, where as in the second example it is the python module name where the operator is defined.
See https://airflow.apache.org/docs/stable/howto/custom-operator.html for more info.
Importing Hooks via plugins is no longer supported
Importing hooks added in plugins via airflow.hooks.<plugin_name>
is no longer supported, and hooks should just be imported as regular python modules.
from airflow.hooks.my_plugin import MyHook
You should instead import it as:
from my_plugin import MyHook
It is still possible (but not required) to "register" hooks in plugins. This is to allow future support for dynamically populating the Connections form in the UI.
See https://airflow.apache.org/docs/stable/howto/custom-operator.html for more info.
Adding Operators and Sensors via plugins is no longer supported
The default value for [core] enable_xcom_pickling
has been changed to False
The pickle type for XCom messages has been replaced to JSON by default to prevent RCE attacks.
Note that JSON serialization is stricter than pickling, so for example if you want to pass
raw bytes through XCom you must encode them using an encoding like base64
.
If you understand the risk and still want to use pickling,
set enable_xcom_pickling = False
in your Airflow config's core
section.
Airflowignore of base path
There was a bug fixed in https://github.com/apache/airflow/pull/11993 that the "airflowignore" checked the base path of the dag folder for forbidden dags, not only the relative part. This had the effect that if the base path contained the excluded word the whole dag folder could have been excluded. For example if the airflowignore file contained x, and the dags folder was '/var/x/dags', then all dags in the folder would be excluded. The fix only matches the relative path only now which means that if you previously used full path as ignored, you should change it to relative one. For example if your dag folder was '/var/dags/' and your airflowignore contained '/var/dag/excluded/', you should change it to 'excluded/'.
ExternalTaskSensor
provides all task context variables to execution_date_fn
as keyword arguments
The old syntax of passing context
as a dictionary will continue to work with the caveat that the argument must be named context
. The following will break. To fix it, change ctx
to context
.
def execution_date_fn(execution_date, ctx):
execution_date_fn
can take in any number of keyword arguments available in the task context dictionary. The following forms of execution_date_fn
are all supported:
def execution_date_fn(dt):
def execution_date_fn(execution_date):
def execution_date_fn(execution_date, ds_nodash):
def execution_date_fn(execution_date, ds_nodash, dag):
The default value for [webserver] cookie_samesite
has been changed to Lax
As recommended by Flask, the
[webserver] cookie_samesite
has bee changed to Lax
from None
.
The 2.0 release of the Airflow is a significant upgrade, and includes substantial major changes, and some of them may be breaking. Existing code written for earlier versions of this project will may require updates to use this version. Sometimes necessary configuration changes are also required. This document describes the changes that have been made, and what you need to do to update your usage.
If you experience issues or have questions, please file an issue.
Major changes
This section describes the major changes that have been made in this release.
Changes to import paths
Formerly the core code was maintained by the original creators - Airbnb. The code that was in the contrib
package was supported by the community. The project was passed to the Apache community and currently the
entire code is maintained by the community, so now the division has no justification, and it is only due
to historical reasons. In Airflow 2.0, we want to organize packages and move integrations
with third party services to the airflow.providers
package.
All changes made are backward compatible, but if you use the old import paths you will see a deprecation warning. The old import paths can be abandoned in the future.
According to AIP-21
_operator
suffix has been removed from operators. A deprecation warning has also been raised for paths
importing with the suffix.
The following table shows changes in import paths.
Old path | New path |
---|---|
airflow.hooks.base_hook.BaseHook | airflow.hooks.base.BaseHook |
airflow.hooks.dbapi_hook.DbApiHook | airflow.hooks.dbapi.DbApiHook |
airflow.operators.dummy_operator.DummyOperator | airflow.operators.dummy.DummyOperator |
airflow.operators.dagrun_operator.TriggerDagRunOperator | airflow.operators.trigger_dagrun.TriggerDagRunOperator |
airflow.operators.branch_operator.BaseBranchOperator | airflow.operators.branch.BaseBranchOperator |
airflow.operators.subdag_operator.SubDagOperator | airflow.operators.subdag.SubDagOperator |
airflow.sensors.base_sensor_operator.BaseSensorOperator | airflow.sensors.base.BaseSensorOperator |
airflow.sensors.date_time_sensor.DateTimeSensor | airflow.sensors.date_time.DateTimeSensor |
airflow.sensors.external_task_sensor.ExternalTaskMarker | airflow.sensors.external_task.ExternalTaskMarker |
airflow.sensors.external_task_sensor.ExternalTaskSensor | airflow.sensors.external_task.ExternalTaskSensor |
airflow.sensors.sql_sensor.SqlSensor | airflow.sensors.sql.SqlSensor |
airflow.sensors.time_delta_sensor.TimeDeltaSensor | airflow.sensors.time_delta.TimeDeltaSensor |
airflow.contrib.sensors.weekday_sensor.DayOfWeekSensor | airflow.sensors.weekday.DayOfWeekSensor |
Database schema changes
In order to migrate the database, you should use the command airflow db upgrade
, but in
some cases manual steps are required.
Unique conn_id in connection table
Previously, Airflow allowed users to add more than one connection with the same conn_id
and on access it would choose one connection randomly. This acted as a basic load balancing and fault tolerance technique, when used in conjunction with retries.
This behavior caused some confusion for users, and there was no clear evidence if it actually worked well or not.
Now the conn_id
will be unique. If you already have duplicates in your metadata database, you will have to manage those duplicate connections before upgrading the database.
Not-nullable conn_type column in connection table
The conn_type
column in the connection
table must contain content. Previously, this rule was enforced
by application logic, but was not enforced by the database schema.
If you made any modifications to the table directly, make sure you don't have null in the conn_type column.
Configuration changes
This release contains many changes that require a change in the configuration of this application or other application that integrate with it.
This section describes the changes that have been made, and what you need to do to.
airflow.contrib.utils.log has been moved
Formerly the core code was maintained by the original creators - Airbnb. The code that was in the contrib
package was supported by the community. The project was passed to the Apache community and currently the
entire code is maintained by the community, so now the division has no justification, and it is only due
to historical reasons. In Airflow 2.0, we want to organize packages and move integrations
with third party services to the airflow.providers
package.
To clean up, the following packages were moved:
Old package | New package |
---|---|
airflow.contrib.utils.log |
airflow.utils.log |
airflow.utils.log.gcs_task_handler |
airflow.providers.google.cloud.log.gcs_task_handler |
airflow.utils.log.wasb_task_handler |
airflow.providers.microsoft.azure.log.wasb_task_handler |
airflow.utils.log.stackdriver_task_handler |
airflow.providers.google.cloud.log.stackdriver_task_handler |
airflow.utils.log.s3_task_handler |
airflow.providers.amazon.aws.log.s3_task_handler |
airflow.utils.log.es_task_handler |
airflow.providers.elasticsearch.log.es_task_handler |
airflow.utils.log.cloudwatch_task_handler |
airflow.providers.amazon.aws.log.cloudwatch_task_handler |
You should update the import paths if you are setting log configurations with the logging_config_class
option.
The old import paths still works but can be abandoned.
SendGrid emailer has been moved
Formerly the core code was maintained by the original creators - Airbnb. The code that was in the contrib package was supported by the community. The project was passed to the Apache community and currently the entire code is maintained by the community, so now the division has no justification, and it is only due to historical reasons.
To clean up, the send_mail
function from the airflow.contrib.utils.sendgrid
module has been moved.
If your configuration file looks like this:
[email]
email_backend = airflow.contrib.utils.sendgrid.send_email
It should look like this now:
[email]
email_backend = airflow.providers.sendgrid.utils.emailer.send_email
The old configuration still works but can be abandoned.
Unify hostname_callable
option in core
section
The previous option used a colon(:
) to split the module from function. Now the dot(.
) is used.
The change aims to unify the format of all options that refer to objects in the airflow.cfg
file.
Custom executors is loaded using full import path
In previous versions of Airflow it was possible to use plugins to load custom executors. It is still
possible, but the configuration has changed. Now you don't have to create a plugin to configure a
custom executor, but you need to provide the full path to the module in the executor
option
in the core
section. The purpose of this change is to simplify the plugin mechanism and make
it easier to configure executor.
If your module was in the path my_acme_company.executors.MyCustomExecutor
and the plugin was
called my_plugin
then your configuration looks like this
[core]
executor = my_plugin.MyCustomExecutor
And now it should look like this:
[core]
executor = my_acme_company.executors.MyCustomExecutor
The old configuration is still works but can be abandoned at any time.
Drop plugin support for stat_name_handler
In previous version, you could use plugins mechanism to configure stat_name_handler
. You should now use the stat_name_handler
option in [scheduler]
section to achieve the same effect.
If your plugin looked like this and was available through the test_plugin
path:
def my_stat_name_handler(stat):
return stat
class AirflowTestPlugin(AirflowPlugin):
name = "test_plugin"
stat_name_handler = my_stat_name_handler
then your airflow.cfg
file should look like this:
[scheduler]
stat_name_handler=test_plugin.my_stat_name_handler
This change is intended to simplify the statsd configuration.
Logging configuration has been moved to new section
The following configurations have been moved from [core]
to the new [logging]
section.
base_log_folder
remote_logging
remote_log_conn_id
remote_base_log_folder
encrypt_s3_logs
logging_level
fab_logging_level
logging_config_class
colored_console_log
colored_log_format
colored_formatter_class
log_format
simple_log_format
task_log_prefix_template
log_filename_template
log_processor_filename_template
dag_processor_manager_log_location
task_log_reader
Metrics configuration has been moved to new section
The following configurations have been moved from [scheduler]
to the new [metrics]
section.
statsd_on
statsd_host
statsd_port
statsd_prefix
statsd_allow_list
stat_name_handler
statsd_datadog_enabled
statsd_datadog_tags
statsd_custom_client_path
Changes to Elasticsearch logging provider
When JSON output to stdout is enabled, log lines will now contain the log_id
& offset
fields, this should make reading task logs from elasticsearch on the webserver work out of the box. Example configuration:
[logging]
remote_logging = True
[elasticsearch]
host = http://es-host:9200
write_stdout = True
json_format = True
Note that the webserver expects the log line data itself to be present in the message
field of the document.
Remove gcp_service_account_keys option in airflow.cfg file
This option has been removed because it is no longer supported by the Google Kubernetes Engine. The new recommended service account keys for the Google Cloud management method is Workload Identity.
Fernet is enabled by default
The fernet mechanism is enabled by default to increase the security of the default installation. In order to
restore the previous behavior, the user must consciously set an empty key in the fernet_key
option of
section [core]
in the airflow.cfg
file.
At the same time, this means that the apache-airflow[crypto]
extra-packages are always installed.
However, this requires that your operating system has libffi-dev
installed.
Changes to propagating Kubernetes worker annotations
kubernetes_annotations
configuration section has been removed.
A new key worker_annotations
has been added to existing kubernetes
section instead.
That is to remove restriction on the character set for k8s annotation keys.
All key/value pairs from kubernetes_annotations
should now go to worker_annotations
as a json. I.e. instead of e.g.
[kubernetes_annotations]
annotation_key = annotation_value
annotation_key2 = annotation_value2
it should be rewritten to
[kubernetes]
worker_annotations = { "annotation_key" : "annotation_value", "annotation_key2" : "annotation_value2" }
Remove run_duration
We should not use the run_duration
option anymore. This used to be for restarting the scheduler from time to time, but right now the scheduler is getting more stable and therefore using this setting is considered bad and might cause an inconsistent state.
Rename pool statsd metrics
Used slot has been renamed to running slot to make the name self-explanatory and the code more maintainable.
This means pool.used_slots.<pool_name>
metric has been renamed to
pool.running_slots.<pool_name>
. The Used Slots
column in Pools Web UI view
has also been changed to Running Slots
.
Removal of Mesos Executor
The Mesos Executor is removed from the code base as it was not widely used and not maintained. Mailing List Discussion on deleting it.
Change dag loading duration metric name
Change DAG file loading duration metric from
dag.loading-duration.<dag_id>
to dag.loading-duration.<dag_file>
. This is to
better handle the case when a DAG file has multiple DAGs.
Sentry is disabled by default
Sentry is disabled by default. To enable these integrations, you need set sentry_on
option
in [sentry]
section to "True"
.
Simplified GCSTaskHandler configuration
In previous versions, in order to configure the service account key file, you had to create a connection entry.
In the current version, you can configure google_key_path
option in [logging]
section to set
the key file path.
Users using Application Default Credentials (ADC) need not take any action.
The change aims to simplify the configuration of logging, to prevent corruption of the instance configuration by changing the value controlled by the user - connection entry. If you configure a backend secret, it also means the webserver doesn't need to connect to it. This simplifies setups with multiple GCP projects, because only one project will require the Secret Manager API to be enabled.
Changes to the core operators/hooks
We strive to ensure that there are no changes that may affect the end user and your files, but this release may contain changes that will require changes to your DAG files.
This section describes the changes that have been made, and what you need to do to update your DAG File, if you use core operators or any other.
BaseSensorOperator now respects the trigger_rule of downstream tasks
Previously, BaseSensorOperator with setting soft_fail=True
skips itself
and skips all its downstream tasks unconditionally, when it fails i.e the trigger_rule of downstream tasks is not
respected.
In the new behavior, the trigger_rule of downstream tasks is respected.
User can preserve/achieve the original behaviour by setting the trigger_rule of each downstream task to all_success
.
BaseOperator uses metaclass
BaseOperator
class uses a BaseOperatorMeta
as a metaclass. This meta class is based on
abc.ABCMeta
. If your custom operator uses different metaclass then you will have to adjust it.
Remove SQL support in BaseHook
Remove get_records
and get_pandas_df
and run
from BaseHook, which only apply for sql like hook,
If want to use them, or your custom hook inherit them, please use airflow.hooks.dbapi.DbApiHook
Assigning task to a DAG using bitwise shift (bit-shift) operators are no longer supported
Previously, you could assign a task to a DAG as follows:
dag = DAG('my_dag')
dummy = DummyOperator(task_id='dummy')
dag >> dummy
This is no longer supported. Instead, we recommend using the DAG as context manager:
with DAG('my_dag') as dag:
dummy = DummyOperator(task_id='dummy')
Removed deprecated import mechanism
The deprecated import mechanism has been removed so the import of modules becomes more consistent and explicit.
For example: from airflow.operators import BashOperator
becomes from airflow.operators.bash_operator import BashOperator
Changes to sensor imports
Sensors are now accessible via airflow.sensors
and no longer via airflow.operators.sensors
.
For example: from airflow.operators.sensors import BaseSensorOperator
becomes from airflow.sensors.base import BaseSensorOperator
Skipped tasks can satisfy wait_for_downstream
Previously, a task instance with wait_for_downstream=True
will only run if the downstream task of
the previous task instance is successful. Meanwhile, a task instance with depends_on_past=True
will run if the previous task instance is either successful or skipped. These two flags are close siblings
yet they have different behavior. This inconsistency in behavior made the API less intuitive to users.
To maintain consistent behavior, both successful or skipped downstream task can now satisfy the
wait_for_downstream=True
flag.
airflow.utils.helpers.cross_downstream
airflow.utils.helpers.chain
The chain
and cross_downstream
methods are now moved to airflow.models.baseoperator module from
airflow.utils.helpers
module.
The baseoperator module seems to be a better choice to keep closely coupled methods together. Helpers module is supposed to contain standalone helper methods that can be imported by all classes.
The chain
method and cross_downstream
method both use BaseOperator. If any other package imports
any classes or functions from helpers module, then it automatically has an
implicit dependency to BaseOperator. That can often lead to cyclic dependencies.
More information in AIRFLOW-6392
In Airflow <2.0 you imported those two methods like this:
from airflow.utils.helpers import chain
from airflow.utils.helpers import cross_downstream
In Airflow 2.0 it should be changed to:
from airflow.models.baseoperator import chain
from airflow.models.baseoperator import cross_downstream
airflow.operators.python.BranchPythonOperator
BranchPythonOperator
will now return a value equal to the task_id
of the chosen branch,
where previously it returned None. Since it inherits from BaseOperator it will do an
xcom_push
of this value if do_xcom_push=True
. This is useful for downstream decision-making.
airflow.sensors.sql_sensor.SqlSensor
SQLSensor now consistent with python bool()
function and the allow_null
parameter has been removed.
It will resolve after receiving any value that is casted to True
with python bool(value)
. That
changes the previous response receiving NULL
or '0'
. Earlier '0'
has been treated as success
criteria. NULL
has been treated depending on value of allow_null
parameter. But all the previous
behaviour is still achievable setting param success
to lambda x: x is None or str(x) not in ('0', '')
.
airflow.operators.trigger_dagrun.TriggerDagRunOperator
The TriggerDagRunOperator now takes a conf
argument to which a dict can be provided as conf for the DagRun.
As a result, the python_callable
argument was removed. PR: https://github.com/apache/airflow/pull/6317.
airflow.operators.python.PythonOperator
provide_context
argument on the PythonOperator was removed. The signature of the callable passed to the PythonOperator is now inferred and argument values are always automatically provided. There is no need to explicitly provide or not provide the context anymore. For example:
def myfunc(execution_date):
print(execution_date)
python_operator = PythonOperator(task_id='mytask', python_callable=myfunc, dag=dag)
Notice you don't have to set provide_context=True, variables from the task context are now automatically detected and provided.
All context variables can still be provided with a double-asterisk argument:
def myfunc(**context):
print(context) # all variables will be provided to context
python_operator = PythonOperator(task_id='mytask', python_callable=myfunc)
The task context variable names are reserved names in the callable function, hence a clash with op_args
and op_kwargs
results in an exception:
def myfunc(dag):
# raises a ValueError because "dag" is a reserved name
# valid signature example: myfunc(mydag)
python_operator = PythonOperator(
task_id='mytask',
op_args=[1],
python_callable=myfunc,
)
The change is backwards compatible, setting provide_context
will add the provide_context
variable to the kwargs
(but won't do anything).
PR: #5990
airflow.sensors.filesystem.FileSensor
FileSensor is now takes a glob pattern, not just a filename. If the filename you are looking for has *
, ?
, or [
in it then you should replace these with [*]
, [?]
, and [[]
.
airflow.operators.subdag_operator.SubDagOperator
SubDagOperator
is changed to use Airflow scheduler instead of backfill
to schedule tasks in the subdag. User no longer need to specify the executor
in SubDagOperator
.
airflow.providers.google.cloud.operators.datastore.CloudDatastoreExportEntitiesOperator
airflow.providers.google.cloud.operators.datastore.CloudDatastoreImportEntitiesOperator
airflow.providers.cncf.kubernetes.operators.kubernetes_pod.KubernetesPodOperator
airflow.providers.ssh.operators.ssh.SSHOperator
airflow.providers.microsoft.winrm.operators.winrm.WinRMOperator
airflow.operators.bash.BashOperator
airflow.providers.docker.operators.docker.DockerOperator
airflow.providers.http.operators.http.SimpleHttpOperator
airflow.providers.http.operators.http.SimpleHttpOperator
The do_xcom_push
flag (a switch to push the result of an operator to xcom or not) was appearing in different incarnations in different operators. It's function has been unified under a common name (do_xcom_push
) on BaseOperator
. This way it is also easy to globally disable pushing results to xcom.
The following operators were affected:
- DatastoreExportOperator (Backwards compatible)
- DatastoreImportOperator (Backwards compatible)
- KubernetesPodOperator (Not backwards compatible)
- SSHOperator (Not backwards compatible)
- WinRMOperator (Not backwards compatible)
- BashOperator (Not backwards compatible)
- DockerOperator (Not backwards compatible)
- SimpleHttpOperator (Not backwards compatible)
See AIRFLOW-3249 for details
airflow.operators.latest_only_operator.LatestOnlyOperator
In previous versions, the LatestOnlyOperator
forcefully skipped all (direct and undirect) downstream tasks on its own. From this version on the operator will only skip direct downstream tasks and the scheduler will handle skipping any further downstream dependencies.
No change is needed if only the default trigger rule all_success
is being used.
If the DAG relies on tasks with other trigger rules (i.e. all_done
) being skipped by the LatestOnlyOperator
, adjustments to the DAG need to be made to commodate the change in behaviour, i.e. with additional edges from the LatestOnlyOperator
.
The goal of this change is to achieve a more consistent and configurale cascading behaviour based on the BaseBranchOperator
(see AIRFLOW-2923 and AIRFLOW-1784).
Changes to the core Python API
We strive to ensure that there are no changes that may affect the end user, and your Python files, but this release may contain changes that will require changes to your plugins, DAG File or other integration.
Only changes unique to this provider are described here. You should still pay attention to the changes that have been made to the core (including core operators) as they can affect the integration behavior of this provider.
This section describes the changes that have been made, and what you need to do to update your Python files.
Removed sub-package imports from airflow/__init__.py
The imports LoggingMixin
, conf
, and AirflowException
have been removed from airflow/__init__.py
.
All implicit references of these objects will no longer be valid. To migrate, all usages of each old path must be
replaced with its corresponding new path.
Old Path (Implicit Import) | New Path (Explicit Import) |
---|---|
airflow.LoggingMixin |
airflow.utils.log.logging_mixin.LoggingMixin |
airflow.conf |
airflow.configuration.conf |
airflow.AirflowException |
airflow.exceptions.AirflowException |
Variables removed from the task instance context
The following variables were removed from the task instance context:
- end_date
- latest_date
- tables
airflow.contrib.utils.Weekday
Formerly the core code was maintained by the original creators - Airbnb. The code that was in the contrib package was supported by the community. The project was passed to the Apache community and currently the entire code is maintained by the community, so now the division has no justification, and it is only due to historical reasons.
To clean up, Weekday
enum has been moved from airflow.contrib.utils
into airflow.utils
module.
airflow.models.connection.Connection
The connection module has new deprecated methods:
Connection.parse_from_uri
Connection.log_info
Connection.debug_info
and one deprecated function:
parse_netloc_to_hostname
Previously, users could create a connection object in two ways
conn_1 = Connection(conn_id="conn_a", uri="mysql://AAA/")
# or
conn_2 = Connection(conn_id="conn_a")
conn_2.parse_uri(uri="mysql://AAA/")
Now the second way is not supported.
Connection.log_info
and Connection.debug_info
method have been deprecated. Read each Connection field individually or use the
default representation (__repr__
).
The old method is still works but can be abandoned at any time. The changes are intended to delete method that are rarely used.
airflow.models.dag.DAG.create_dagrun
DAG.create_dagrun accepts run_type and does not require run_id
This change is caused by adding run_type
column to DagRun
.
Previous signature:
def create_dagrun(self,
run_id,
state,
execution_date=None,
start_date=None,
external_trigger=False,
conf=None,
session=None):
current:
def create_dagrun(self,
state,
execution_date=None,
run_id=None,
start_date=None,
external_trigger=False,
conf=None,
run_type=None,
session=None):
- If user provides
run_id
then therun_type
will be derived from it by checking prefix, allowed types manual
,scheduled
,backfill
(defined byairflow.utils.types.DagRunType
).
If user provides run_type
and execution_date
then run_id
is constructed as
{run_type}__{execution_data.isoformat()}
.
Airflow should construct dagruns using run_type
and execution_date
, creation using
run_id
is preserved for user actions.
airflow.models.dagrun.DagRun
Use DagRunType.SCHEDULED.value instead of DagRun.ID_PREFIX
All the run_id prefixes for different kind of DagRuns have been grouped into a single
enum in airflow.utils.types.DagRunType
.
Previously, there were defined in various places, example as ID_PREFIX
class variables for
DagRun
, BackfillJob
and in _trigger_dag
function.
Was:
>> from airflow.models.dagrun import DagRun
>> DagRun.ID_PREFIX
scheduled__
Replaced by:
>> from airflow.utils.types import DagRunType
>> DagRunType.SCHEDULED.value
scheduled
airflow.utils.file.TemporaryDirectory
We remove airflow.utils.file.TemporaryDirectory
Since Airflow dropped support for Python < 3.5 there's no need to have this custom
implementation of TemporaryDirectory
because the same functionality is provided by
tempfile.TemporaryDirectory
.
Now users instead of import from airflow.utils.files import TemporaryDirectory
should
do from tempfile import TemporaryDirectory
. Both context managers provide the same
interface, thus no additional changes should be required.
airflow.AirflowMacroPlugin
We removed airflow.AirflowMacroPlugin
class. The class was there in airflow package but it has not been used (apparently since 2015).
It has been removed.
airflow.settings.CONTEXT_MANAGER_DAG
CONTEXT_MANAGER_DAG was removed from settings. It's role has been taken by DagContext
in
'airflow.models.dag'. One of the reasons was that settings should be rather static than store
dynamic context from the DAG, but the main one is that moving the context out of settings allowed to
untangle cyclic imports between DAG, BaseOperator, SerializedDAG, SerializedBaseOperator which was
part of AIRFLOW-6010.
airflow.utils.log.logging_mixin.redirect_stderr
airflow.utils.log.logging_mixin.redirect_stdout
Function redirect_stderr
and redirect_stdout
from airflow.utils.log.logging_mixin
module has
been deleted because it can be easily replaced by the standard library.
The functions of the standard library are more flexible and can be used in larger cases.
The code below
import logging
from airflow.utils.log.logging_mixin import redirect_stderr, redirect_stdout
logger = logging.getLogger("custom-logger")
with redirect_stdout(logger, logging.INFO), redirect_stderr(logger, logging.WARN):
print("I love Airflow")
can be replaced by the following code:
from contextlib import redirect_stdout, redirect_stderr
import logging
from airflow.utils.log.logging_mixin import StreamLogWriter
logger = logging.getLogger("custom-logger")
with redirect_stdout(StreamLogWriter(logger, logging.INFO)), \
redirect_stderr(StreamLogWriter(logger, logging.WARN)):
print("I Love Airflow")
airflow.models.baseoperator.BaseOperator
Now, additional arguments passed to BaseOperator cause an exception. Previous versions of Airflow took additional arguments and displayed a message on the console. When the message was not noticed by users, it caused very difficult to detect errors.
In order to restore the previous behavior, you must set an True
in the allow_illegal_arguments
option of section [operators]
in the airflow.cfg
file. In the future it is possible to completely
delete this option.
airflow.models.dagbag.DagBag
Passing store_serialized_dags
argument to DagBag.init and accessing DagBag.store_serialized_dags
property
are deprecated and will be removed in future versions.
Previous signature:
DagBag(
dag_folder=None,
include_examples=conf.getboolean('core', 'LOAD_EXAMPLES'),
safe_mode=conf.getboolean('core', 'DAG_DISCOVERY_SAFE_MODE'),
store_serialized_dags=False
):
current:
DagBag(
dag_folder=None,
include_examples=conf.getboolean('core', 'LOAD_EXAMPLES'),
safe_mode=conf.getboolean('core', 'DAG_DISCOVERY_SAFE_MODE'),
read_dags_from_db=False
):
If you were using positional arguments, it requires no change but if you were using keyword
arguments, please change store_serialized_dags
to read_dags_from_db
.
Similarly, if you were using DagBag().store_serialized_dags
property, change it to
DagBag().read_dags_from_db
.
Changes in google
provider package
We strive to ensure that there are no changes that may affect the end user and your Python files, but this release may contain changes that will require changes to your configuration, DAG Files or other integration e.g. custom operators.
Only changes unique to this provider are described here. You should still pay attention to the changes that have been made to the core (including core operators) as they can affect the integration behavior of this provider.
This section describes the changes that have been made, and what you need to do to update your if you use operators or hooks which integrate with Google services (including Google Cloud - GCP).
Direct impersonation added to operators communicating with Google services
Directly impersonating a service account
has been made possible for operators communicating with Google services via new argument called impersonation_chain
(google_impersonation_chain
in case of operators that also communicate with services of other cloud providers).
As a result, GCSToS3Operator no longer derivatives from GCSListObjectsOperator.
Normalize gcp_conn_id for Google Cloud
Previously not all hooks and operators related to Google Cloud use
gcp_conn_id
as parameter for GCP connection. There is currently one parameter
which apply to most services. Parameters like datastore_conn_id
, bigquery_conn_id
,
google_cloud_storage_conn_id
and similar have been deprecated. Operators that require two connections are not changed.
Following components were affected by normalization:
- airflow.providers.google.cloud.hooks.datastore.DatastoreHook
- airflow.providers.google.cloud.hooks.bigquery.BigQueryHook
- airflow.providers.google.cloud.hooks.gcs.GoogleCloudStorageHook
- airflow.providers.google.cloud.operators.bigquery.BigQueryCheckOperator

- airflow.operators.gcs_to_s3.GoogleCloudStorageToS3Operator
- airflow.operators.gcs_to_gcs.GoogleCloudStorageToGoogleCloudStorageOperator
- airflow.operators.bigquery_to_gcs.BigQueryToCloudStorageOperator
- airflow.operators.local_to_gcs.FileToGoogleCloudStorageOperator
- airflow.operators.cassandra_to_gcs.CassandraToGoogleCloudStorageOperator
- airflow.operators.bigquery_to_bigquery.BigQueryToBigQueryOperator

Unify default conn_id for Google Cloud
Previously not all hooks and operators related to Google Cloud use
google_cloud_default
as a default conn_id. There is currently one default
variant. Values like google_cloud_storage_default
, bigquery_default
,
google_cloud_datastore_default
have been deprecated. The configuration of
existing relevant connections in the database have been preserved. To use those
deprecated GCP conn_id, you need to explicitly pass their conn_id into
operators/hooks. Otherwise, google_cloud_default
will be used as GCP's conn_id
by default.
airflow.providers.google.cloud.hooks.dataflow.DataflowHook
airflow.providers.google.cloud.operators.dataflow.DataflowCreateJavaJobOperator
airflow.providers.google.cloud.operators.dataflow.DataflowTemplatedJobStartOperator
airflow.providers.google.cloud.operators.dataflow.DataflowCreatePythonJobOperator
To use project_id argument consistently across GCP hooks and operators, we did the following changes:
- Changed order of arguments in DataflowHook.start_python_dataflow. Uses with positional arguments may break.
- Changed order of arguments in DataflowHook.is_job_dataflow_running. Uses with positional arguments may break.
- Changed order of arguments in DataflowHook.cancel_job. Uses with positional arguments may break.
- Added optional project_id argument to DataflowCreateJavaJobOperator constructor.
- Added optional project_id argument to DataflowTemplatedJobStartOperator constructor.
- Added optional project_id argument to DataflowCreatePythonJobOperator constructor.
airflow.providers.google.cloud.sensors.gcs.GCSUploadSessionCompleteSensor
To provide more precise control in handling of changes to objects in underlying GCS Bucket the constructor of this sensor now has changed.
- Old Behavior: This constructor used to optionally take
previous_num_objects: int
. - New replacement constructor kwarg:
previous_objects: Optional[Set[str]]
.
Most users would not specify this argument because the bucket begins empty and the user wants to treat any files as new.
Example of Updating usage of this sensor: Users who used to call:
GCSUploadSessionCompleteSensor(bucket='my_bucket', prefix='my_prefix', previous_num_objects=1)
Will now call:
GCSUploadSessionCompleteSensor(bucket='my_bucket', prefix='my_prefix', previous_num_objects={'.keep'})
Where '.keep' is a single file at your prefix that the sensor should not consider new.
airflow.providers.google.cloud.hooks.bigquery.BigQueryBaseCursor
airflow.providers.google.cloud.hooks.bigquery.BigQueryHook
To simplify BigQuery operators (no need of Cursor
) and standardize usage of hooks within all GCP integration methods from BiqQueryBaseCursor
were moved to BigQueryHook
. Using them by from Cursor
object is still possible due to preserved backward compatibility but they will raise DeprecationWarning
.
The following methods were moved:
Old path | New path |
---|---|
airflow.providers.google.cloud.hooks.bigquery.BigQueryBaseCursor.cancel_query | airflow.providers.google.cloud.hooks.bigquery.BigQueryHook.cancel_query |

airflow.providers.google.cloud.hooks.bigquery.BigQueryBaseCursor
Since BigQuery is the part of the GCP it was possible to simplify the code by handling the exceptions
by usage of the airflow.providers.google.common.hooks.base.GoogleBaseHook.catch_http_exception
decorator however it changes
exceptions raised by the following methods:
airflow.providers.google.cloud.hooks.bigquery.BigQueryBaseCursor.run_table_delete
raisesAirflowException
instead ofException
.airflow.providers.google.cloud.hooks.bigquery.BigQueryBaseCursor.create_empty_dataset
raisesAirflowException
instead ofValueError
.airflow.providers.google.cloud.hooks.bigquery.BigQueryBaseCursor.get_dataset
raisesAirflowException
instead ofValueError
.
airflow.providers.google.cloud.operators.bigquery.BigQueryCreateEmptyTableOperator
airflow.providers.google.cloud.operators.bigquery.BigQueryCreateEmptyDatasetOperator
Idempotency was added to BigQueryCreateEmptyTableOperator
and BigQueryCreateEmptyDatasetOperator
.
But to achieve that try / except clause was removed from create_empty_dataset
and create_empty_table
methods of BigQueryHook
.
airflow.providers.google.cloud.hooks.dataflow.DataflowHook
airflow.providers.google.cloud.hooks.mlengine.MLEngineHook
airflow.providers.google.cloud.hooks.pubsub.PubSubHook
The change in GCP operators implies that GCP Hooks for those operators require now keyword parameters rather
than positional ones in all methods where project_id
is used. The methods throw an explanatory exception
in case they are called using positional parameters.
Other GCP hooks are unaffected.
airflow.providers.google.cloud.hooks.pubsub.PubSubHook
airflow.providers.google.cloud.operators.pubsub.PubSubTopicCreateOperator
airflow.providers.google.cloud.operators.pubsub.PubSubSubscriptionCreateOperator
airflow.providers.google.cloud.operators.pubsub.PubSubTopicDeleteOperator
airflow.providers.google.cloud.operators.pubsub.PubSubSubscriptionDeleteOperator
airflow.providers.google.cloud.operators.pubsub.PubSubPublishOperator
airflow.providers.google.cloud.sensors.pubsub.PubSubPullSensor
In the PubSubPublishOperator
and PubSubHook.publsh
method the data field in a message should be bytestring (utf-8 encoded) rather than base64 encoded string.
Due to the normalization of the parameters within GCP operators and hooks a parameters like project
or topic_project
are deprecated and will be substituted by parameter project_id
.
In PubSubHook.create_subscription
hook method in the parameter subscription_project
is replaced by subscription_project_id
.
Template fields are updated accordingly and old ones may not work.
It is required now to pass key-word only arguments to PubSub
hook.
These changes are not backward compatible.
airflow.providers.google.cloud.operators.kubernetes_engine.GKEStartPodOperator
The gcp_conn_id parameter in GKEPodOperator is required. In previous versions, it was possible to pass
the None
value to the gcp_conn_id
in the GKEStartPodOperator
operator, which resulted in credentials being determined according to the
Application Default Credentials strategy.
Now this parameter requires a value. To restore the previous behavior, configure the connection without specifying the service account.
Detailed information about connection management is available: Google Cloud Connection.
airflow.providers.google.cloud.hooks.gcs.GCSHook
-
The following parameters have been replaced in all the methods in GCSHook:
bucket
is changed tobucket_name
object
is changed toobject_name
-
The
maxResults
parameter inGoogleCloudStorageHook.list
has been renamed tomax_results
for consistency.
airflow.providers.google.cloud.operators.dataproc.DataprocSubmitPigJobOperator
airflow.providers.google.cloud.operators.dataproc.DataprocSubmitHiveJobOperator
airflow.providers.google.cloud.operators.dataproc.DataprocSubmitSparkSqlJobOperator
airflow.providers.google.cloud.operators.dataproc.DataprocSubmitSparkJobOperator
airflow.providers.google.cloud.operators.dataproc.DataprocSubmitHadoopJobOperator
airflow.providers.google.cloud.operators.dataproc.DataprocSubmitPySparkJobOperator
The 'properties' and 'jars' properties for the Dataproc related operators (DataprocXXXOperator
) have been renamed from
dataproc_xxxx_properties
and dataproc_xxx_jars
to dataproc_properties
and dataproc_jars
respectively.
Arguments for dataproc_properties dataproc_jars
airflow.providers.google.cloud.operators.cloud_storage_transfer_service.CloudDataTransferServiceCreateJobOperator
To obtain pylint compatibility the filter
argument in CloudDataTransferServiceCreateJobOperator
has been renamed to request_filter
.
airflow.providers.google.cloud.hooks.cloud_storage_transfer_service.CloudDataTransferServiceHook
To obtain pylint compatibility the filter
argument in CloudDataTransferServiceHook.list_transfer_job
and
CloudDataTransferServiceHook.list_transfer_operations
has been renamed to request_filter
.
airflow.providers.google.cloud.hooks.bigquery.BigQueryHook
In general all hook methods are decorated with @GoogleBaseHook.fallback_to_default_project_id
thus
parameters to hook can only be passed via keyword arguments.
create_empty_table
method accepts nowtable_resource
parameter. If provided all other parameters are ignored.create_empty_dataset
will now use values fromdataset_reference
instead of raising error if parameters were passed indataset_reference
and as arguments to method. Additionally validation ofdataset_reference
is done usingDataset.from_api_repr
. Exception and log messages has been changed.update_dataset
requires now newfields
argument (breaking change)delete_dataset
has new signature (dataset_id, project_id, ...) previous one was (project_id, dataset_id, ...) (breaking change)get_tabledata
returns list of rows instead of API response in dict format. This method is deprecated in favor oflist_rows
. (breaking change)
airflow.providers.google.cloud.hooks.dataflow.DataflowHook.start_python_dataflow
airflow.providers.google.cloud.hooks.dataflow.DataflowHook.start_python_dataflow
airflow.providers.google.cloud.operators.dataflow.DataflowCreatePythonJobOperator
Change python3 as Dataflow Hooks/Operators default interpreter
Now the py_interpreter
argument for DataFlow Hooks/Operators has been changed from python2 to python3.
airflow.providers.google.common.hooks.base_google.GoogleBaseHook
To simplify the code, the decorator provide_gcp_credential_file has been moved from the inner-class.
Instead of @GoogleBaseHook._Decorators.provide_gcp_credential_file
,
you should write @GoogleBaseHook.provide_gcp_credential_file
airflow.providers.google.cloud.operators.dataproc.DataprocCreateClusterOperator
It is highly recommended to have 1TB+ disk size for Dataproc to have sufficient throughput: https://cloud.google.com/compute/docs/disks/performance
Hence, the default value for master_disk_size
in DataprocCreateClusterOperator
has been changed from 500GB to 1TB.
<airflow class="providers google c"></airflow>loud.operators.bigquery.BigQueryGetDatasetTablesOperator
We changed signature of BigQueryGetDatasetTablesOperator.
Before:
BigQueryGetDatasetTablesOperator(dataset_id: str, dataset_resource: dict, ...)
After:
BigQueryGetDatasetTablesOperator(dataset_resource: dict, dataset_id: Optional[str] = None, ...)
Changes in amazon
provider package
We strive to ensure that there are no changes that may affect the end user, and your Python files, but this release may contain changes that will require changes to your configuration, DAG Files or other integration e.g. custom operators.
Only changes unique to this provider are described here. You should still pay attention to the changes that have been made to the core (including core operators) as they can affect the integration behavior of this provider.
This section describes the changes that have been made, and what you need to do to update your if you use operators or hooks which integrate with Amazon services (including Amazon Web Service - AWS).
Migration of AWS components
All AWS components (hooks, operators, sensors, example DAGs) will be grouped together as decided in
AIP-21. Migrated
components remain backwards compatible but raise a DeprecationWarning
when imported from the old module.
Migrated are:

airflow.providers.amazon.aws.hooks.emr.EmrHook
airflow.providers.amazon.aws.operators.emr_add_steps.EmrAddStepsOperator
airflow.providers.amazon.aws.operators.emr_create_job_flow.EmrCreateJobFlowOperator
airflow.providers.amazon.aws.operators.emr_terminate_job_flow.EmrTerminateJobFlowOperator
The default value for the aws_conn_id was accidentally set to 's3_default' instead of 'aws_default' in some of the emr operators in previous versions. This was leading to EmrStepSensor not being able to find their corresponding emr cluster. With the new changes in the EmrAddStepsOperator, EmrTerminateJobFlowOperator and EmrCreateJobFlowOperator this issue is solved.
airflow.providers.amazon.aws.operators.batch.AwsBatchOperator
The AwsBatchOperator
was refactored to extract an AwsBatchClient
(and inherit from it). The
changes are mostly backwards compatible and clarify the public API for these classes; some
private methods on AwsBatchOperator
for polling a job status were relocated and renamed
to surface new public methods on AwsBatchClient
(and via inheritance on AwsBatchOperator
). A
couple of job attributes are renamed on an instance of AwsBatchOperator
; these were mostly
used like private attributes but they were surfaced in the public API, so any use of them needs
to be updated as follows:
AwsBatchOperator().jobId
->AwsBatchOperator().job_id
AwsBatchOperator().jobName
->AwsBatchOperator().job_name
The AwsBatchOperator
gets a new option to define a custom model for waiting on job status changes.
The AwsBatchOperator
can use a new waiters
parameter, an instance of AwsBatchWaiters
, to
specify that custom job waiters will be used to monitor a batch job. See the latest API
documentation for details.
airflow.providers.amazon.aws.sensors.athena.AthenaSensor
Replace parameter max_retires
with max_retries
to fix typo.
airflow.providers.amazon.aws.hooks.s3.S3Hook
Note: The order of arguments has changed for check_for_prefix
.
The bucket_name
is now optional. It falls back to the connection schema
attribute.
The delete_objects
now returns None
instead of a response, since the method now makes multiple api requests when the keys list length is > 1000.
Changes in other provider packages
We strive to ensure that there are no changes that may affect the end user and your Python files, but this release may contain changes that will require changes to your configuration, DAG Files or other integration e.g. custom operators.
Only changes unique to providers are described here. You should still pay attention to the changes that have been made to the core (including core operators) as they can affect the integration behavior of this provider.
This section describes the changes that have been made, and what you need to do to update your if
you use any code located in airflow.providers
package.
Changed return type of list_prefixes
and list_keys
methods in S3Hook
Previously, the list_prefixes
and list_keys
methods returned None
when there were no
results. The behavior has been changed to return an empty list instead of None
in this
case.
Removed Hipchat integration
Hipchat has reached end of life and is no longer available.
For more information please see https://community.atlassian.com/t5/Stride-articles/Stride-and-Hipchat-Cloud-have-reached-End-of-Life-updated/ba-p/940248
airflow.providers.salesforce.hooks.salesforce.SalesforceHook
Replace parameter sandbox
with domain
. According to change in simple-salesforce package.
Rename sign_in
function to get_conn
.
airflow.providers.apache.pinot.hooks.pinot.PinotAdminHook.create_segment
Rename parameter name from format
to segment_format
in PinotAdminHook function create_segment fro pylint compatible
airflow.providers.apache.hive.hooks.hive.HiveMetastoreHook.get_partitions
Rename parameter name from filter
to partition_filter
in HiveMetastoreHook function get_partitions for pylint compatible
airflow.providers.ftp.hooks.ftp.FTPHook.list_directory
Remove unnecessary parameter nlst
in FTPHook function list_directory
for pylint compatible
airflow.providers.postgres.hooks.postgres.PostgresHook.copy_expert
Remove unnecessary parameter open
in PostgresHook function copy_expert
for pylint compatible
airflow.providers.opsgenie.operators.opsgenie_alert.OpsgenieAlertOperator
Change parameter name from visibleTo
to visible_to
in OpsgenieAlertOperator for pylint compatible
airflow.providers.imap.hooks.imap.ImapHook
airflow.providers.imap.sensors.imap_attachment.ImapAttachmentSensor
ImapHook:
- The order of arguments has changed for
has_mail_attachment
,retrieve_mail_attachments
anddownload_mail_attachments
. - A new
mail_filter
argument has been added to each of those.
airflow.providers.http.hooks.http.HttpHook
The HTTPHook is now secured by default: verify=True
(before: verify=False
)
This can be overwriten by using the extra_options param as {'verify': False}
.
airflow.providers.cloudant.hooks.cloudant.CloudantHook
- upgraded cloudant version from
>=0.5.9,<2.0
to>=2.0
- removed the use of the
schema
attribute in the connection - removed
db
function since the database object can also be retrieved by callingcloudant_session['database_name']
For example:
from airflow.providers.cloudant.hooks.cloudant import CloudantHook
with CloudantHook().get_conn() as cloudant_session:
database = cloudant_session['database_name']
See the docs for more information on how to use the new cloudant version.
airflow.providers.snowflake
When initializing a Snowflake hook or operator, the value used for snowflake_conn_id
was always snowflake_conn_id
, regardless of whether or not you specified a value for it. The default snowflake_conn_id
value is now switched to snowflake_default
for consistency and will be properly overridden when specified.
Other changes
This release also includes changes that fall outside any of the sections above.
Standardised "extra" requirements
We standardised the Extras names and synchronized providers package names with the main airflow extras.
We deprecated a number of extras in 2.0.
Deprecated extras | New extras |
---|---|
atlas | apache.atlas |
aws | amazon |
azure | microsoft.azure |
azure_blob_storage | microsoft.azure |
azure_data_lake | microsoft.azure |
azure_cosmos | microsoft.azure |
azure_container_instances | microsoft.azure |
cassandra | apache.cassandra |
druid | apache.druid |
gcp | |
gcp_api | |
hdfs | apache.hdfs |
hive | apache.hive |
kubernetes | cncf.kubernetes |
mssql | microsoft.mssql |
pinot | apache.pinot |
webhdfs | apache.webhdfs |
winrm | apache.winrm |
For example:
If you want to install integration for Microsoft Azure, then instead of pip install apache-airflow[atlas]
you should use pip install apache-airflow[apache.atlas]
.
NOTE!
On November 2020, new version of PIP (20.3) has been released with a new, 2020 resolver. This resolver
does not yet work with Apache Airflow and might leads to errors in installation - depends on your choice
of extras. In order to install Airflow you need to either downgrade pip to version 20.2.4
pip install --upgrade pip==20.2.4
or, in case you use Pip 20.3, you need to add option
--use-deprecated legacy-resolver
to your pip install command.
If you want to install integration for Microsoft Azure, then instead of
pip install 'apache-airflow[azure_blob_storage,azure_data_lake,azure_cosmos,azure_container_instances]'
you should execute pip install 'apache-airflow[azure]'
If you want to install integration for Amazon Web Services, then instead of
pip install 'apache-airflow[s3,emr]'
, you should execute pip install 'apache-airflow[aws]'
The deprecated extras will be removed in 3.0.
Simplify the response payload of endpoints /dag_stats and /task_stats
The response of endpoints /dag_stats
and /task_stats
help UI fetch brief statistics about DAGs and Tasks. The format was like
{
"example_http_operator": [
{
"state": "success",
"count": 0,
"dag_id": "example_http_operator",
"color": "green"
},
{
"state": "running",
"count": 0,
"dag_id": "example_http_operator",
"color": "lime"
},
...
],
...
}
The dag_id
was repeated in the payload, which makes the response payload unnecessarily bigger.
Now the dag_id
will not appear repeated in the payload, and the response format is like
{
"example_http_operator": [
{
"state": "success",
"count": 0,
"color": "green"
},
{
"state": "running",
"count": 0,
"color": "lime"
},
...
],
...
}
Airflow 1.10.14
[scheduler] max_threads
config has been renamed to [scheduler] parsing_processes
From Airflow 1.10.14, max_threads
config under [scheduler]
section has been renamed to parsing_processes
.
This is to align the name with the actual code where the Scheduler launches the number of processes defined by
[scheduler] parsing_processes
to parse the DAG files.
Airflow CLI changes in line with 2.0
The Airflow CLI has been organized so that related commands are grouped together as subcommands, which means that if you use these commands in your scripts, they will now raise a DeprecationWarning and you have to make changes to them before you upgrade to Airflow 2.0.
This section describes the changes that have been made, and what you need to do to update your script.
The ability to manipulate users from the command line has been changed. airflow create_user
, airflow delete_user
and airflow list_users
has been grouped to a single command airflow users
with optional flags create
, list
and delete
.
The airflow list_dags
command is now airflow dags list
, airflow pause
is airflow dags pause
, etc.
In Airflow 1.10 and 2.0 there is an airflow config
command but there is a difference in behavior. In Airflow 1.10,
it prints all config options while in Airflow 2.0, it's a command group. airflow config
is now airflow config list
.
You can check other options by running the command airflow config --help
Compatibility with the old CLI has been maintained, but they will no longer appear in the help
You can learn about the commands by running airflow --help
. For example to get help about the celery
group command,
you have to run the help command: airflow celery --help
.

Airflow 1.10.13
TimeSensor is now timezone aware
Previously TimeSensor
always compared the target_time
with the current time in UTC.
Now it will compare target_time
with the current time in the timezone of the DAG,
defaulting to the default_timezone
in the global config.
Removed Kerberos support for HDFS hook
The HDFS hook's Kerberos support has been removed due to removed python-krbV dependency from PyPI and generally lack of support for SSL in Python3 (Snakebite-py3 we use as dependency has no support for SSL connection to HDFS).
SSL support still works for WebHDFS hook.
Unify user session lifetime configuration
In previous version of Airflow user session lifetime could be configured by
session_lifetime_days
and force_log_out_after
options. In practise only session_lifetime_days
had impact on session lifetime, but it was limited to values in day.
We have removed mentioned options and introduced new session_lifetime_minutes
option which simplify session lifetime configuration.
Before
[webserver]
force_log_out_after = 0
session_lifetime_days = 30
After
[webserver]
session_lifetime_minutes = 43200
Adding Operators, Hooks and Sensors via Airflow Plugins is deprecated
The ability to import Operators, Hooks and Sensors via the plugin mechanism has been deprecated and will raise warnings in Airflow 1.10.13 and will be removed completely in Airflow 2.0.
Check https://airflow.apache.org/docs/1.10.13/howto/custom-operator.html to see how you can create and import Custom Hooks, Operators and Sensors.
Airflow 1.10.12
Clearing tasks skipped by SkipMixin will skip them
Previously, when tasks skipped by SkipMixin (such as BranchPythonOperator, BaseBranchOperator and ShortCircuitOperator) are cleared, they execute. Since 1.10.12, when such skipped tasks are cleared, they will be skipped again by the newly introduced NotPreviouslySkippedDep.
The pod_mutation_hook function will now accept a kubernetes V1Pod object
As of airflow 1.10.12, using the airflow.contrib.kubernetes.Pod
class in the pod_mutation_hook
is now deprecated. Instead we recommend that users
treat the pod
parameter as a kubernetes.client.models.V1Pod
object. This means that users now have access to the full Kubernetes API
when modifying airflow pods
pod_template_file option now available in the KubernetesPodOperator
Users can now offer a path to a yaml for the KubernetesPodOperator using the pod_template_file
parameter.
Airflow 1.10.11
Use NULL as default value for dag.description
Now use NULL as default value for dag.description in dag table
Restrict editing DagRun State in the old UI (Flask-admin based UI)
Before 1.10.11 it was possible to edit DagRun State in the /admin/dagrun/
page
to any text.
In Airflow 1.10.11+, the user can only choose the states from the list.
Experimental API will deny all request by default.
The previous default setting was to allow all API requests without authentication, but this poses security risks to users who miss this fact. This changes the default for new installs to deny all requests by default.
Note: This will not change the behavior for existing installs, please update check your airflow.cfg
If you wish to have the experimental API work, and aware of the risks of enabling this without authentication (or if you have your own authentication layer in front of Airflow) you can get the previous behaviour on a new install by setting this in your airflow.cfg:
[api]
auth_backend = airflow.api.auth.backend.default
XCom Values can no longer be added or changed from the Webserver
Since XCom values can contain pickled data, we would no longer allow adding or changing XCom values from the UI.
Default for run_as_user
configured has been changed to 50000 from 0
The UID to run the first process of the Worker PODs when using has been changed to 50000
from the previous default of 0
. The previous default was an empty string but the code used 0
if it was
empty string.
Before:
[kubernetes]
run_as_user =
After:
[kubernetes]
run_as_user = 50000
This is done to avoid running the container as root
user.
Airflow 1.10.10
Setting Empty string to a Airflow Variable will return an empty string
Previously when you set an Airflow Variable with an empty string (''
), the value you used to get
back was None
. This will now return an empty string ('''
)
Example:
>> Variable.set('test_key', '')
>> Variable.get('test_key')
The above code returned None
previously, now it will return ''
.
Make behavior of none_failed
trigger rule consistent with documentation
The behavior of the none_failed
trigger rule is documented as "all parents have not failed (failed
or
upstream_failed
) i.e. all parents have succeeded or been skipped." As previously implemented, the actual behavior
would skip if all parents of a task had also skipped.
Add new trigger rule none_failed_or_skipped
The fix to none_failed
trigger rule breaks workflows that depend on the previous behavior.
If you need the old behavior, you should change the tasks with none_failed
trigger rule to none_failed_or_skipped
.
Success Callback will be called when a task in marked as success from UI
When a task is marked as success by a user from Airflow UI - on_success_callback
will be called
Airflow 1.10.9
No breaking changes.
Airflow 1.10.8
Failure callback will be called when task is marked failed
When task is marked failed by user or task fails due to system failures - on failure call back will be called as part of clean up
See AIRFLOW-5621 for details
Airflow 1.10.7
Changes in experimental API execution_date microseconds replacement
The default behavior was to strip the microseconds (and milliseconds, etc) off of all dag runs triggered by
by the experimental REST API. The default behavior will change when an explicit execution_date is
passed in the request body. It will also now be possible to have the execution_date generated, but
keep the microseconds by sending replace_microseconds=false
in the request body. The default
behavior can be overridden by sending replace_microseconds=true
along with an explicit execution_date
Infinite pool size and pool size query optimisation
Pool size can now be set to -1 to indicate infinite size (it also includes optimisation of pool query which lead to poor task n^2 performance of task pool queries in MySQL).
Viewer won't have edit permissions on DAG view.
Google Cloud Storage Hook
The GoogleCloudStorageDownloadOperator
can either write to a supplied filename
or
return the content of a file via xcom through store_to_xcom_key
- both options are mutually exclusive.
Airflow 1.10.6
BaseOperator::render_template function signature changed
Previous versions of the BaseOperator::render_template
function required an attr
argument as the first
positional argument, along with content
and context
. This function signature was changed in 1.10.6 and
the attr
argument is no longer required (or accepted).
In order to use this function in subclasses of the BaseOperator
, the attr
argument must be removed:
result = self.render_template('myattr', self.myattr, context) # Pre-1.10.6 call
...
result = self.render_template(self.myattr, context) # Post-1.10.6 call
Changes to aws_default
Connection's default region
The region of Airflow's default connection to AWS (aws_default
) was previously
set to us-east-1
during installation.
The region now needs to be set manually, either in the connection screens in
Airflow, via the ~/.aws
config files, or via the AWS_DEFAULT_REGION
environment
variable.
Some DAG Processing metrics have been renamed
The following metrics are deprecated and won't be emitted in Airflow 2.0:
scheduler.dagbag.errors
anddagbag_import_errors
-- usedag_processing.import_errors
insteaddag_file_processor_timeouts
-- usedag_processing.processor_timeouts
insteadcollect_dags
-- usedag_processing.total_parse_time
insteaddag.loading-duration.<basename>
-- usedag_processing.last_duration.<basename>
insteaddag_processing.last_runtime.<basename>
-- usedag_processing.last_duration.<basename>
instead
Airflow 1.10.5
No breaking changes.
Airflow 1.10.4
Export MySQL timestamps as UTC
MySqlToGoogleCloudStorageOperator
now exports TIMESTAMP columns as UTC
by default, rather than using the default timezone of the MySQL server.
This is the correct behavior for use with BigQuery, since BigQuery
assumes that TIMESTAMP columns without time zones are in UTC. To
preserve the previous behavior, set ensure_utc
to False.
Changes to DatastoreHook
- removed argument
version
fromget_conn
function and added it to the hook's__init__
function instead and renamed it toapi_version
- renamed the
partialKeys
argument of functionallocate_ids
topartial_keys
Changes to GoogleCloudStorageHook
-
the discovery-based api (
googleapiclient.discovery
) used inGoogleCloudStorageHook
is now replaced by the recommended client based api (google-cloud-storage
). To know the difference between both the libraries, read https://cloud.google.com/apis/docs/client-libraries-explained. PR: #5054 -
as a part of this replacement, the
multipart
&num_retries
parameters forGoogleCloudStorageHook.upload
method have been deprecated.The client library uses multipart upload automatically if the object/blob size is more than 8 MB - source code. The client also handles retries automatically
-
the
generation
parameter is deprecated inGoogleCloudStorageHook.delete
andGoogleCloudStorageHook.insert_object_acl
.
Updating to google-cloud-storage >= 1.16
changes the signature of the upstream client.get_bucket()
method from get_bucket(bucket_name: str)
to get_bucket(bucket_or_name: Union[str, Bucket])
. This method is not directly exposed by the airflow hook, but any code accessing the connection directly (GoogleCloudStorageHook().get_conn().get_bucket(...)
or similar) will need to be updated.
Changes in writing Logs to Elasticsearch
The elasticsearch_
prefix has been removed from all config items under the [elasticsearch]
section. For example elasticsearch_host
is now just host
.
Removal of non_pooled_task_slot_count
and non_pooled_backfill_task_slot_count
non_pooled_task_slot_count
and non_pooled_backfill_task_slot_count
are removed in favor of a real pool, e.g. default_pool
.
By default tasks are running in default_pool
.
default_pool
is initialized with 128 slots and user can change the
number of slots through UI/CLI. default_pool
cannot be removed.
pool
config option in Celery section to support different Celery pool implementation
The new pool
config option allows users to choose different pool
implementation. Default value is "prefork", while choices include "prefork" (default),
"eventlet", "gevent" or "solo". This may help users achieve better concurrency performance
in different scenarios.
For more details about Celery pool implementation, please refer to:
- https://docs.celeryproject.org/en/latest/userguide/workers.html#concurrency
- https://docs.celeryproject.org/en/latest/userguide/concurrency/eventlet.html
Change to method signature in BaseOperator
and DAG
classes
The signature of the get_task_instances
method in the BaseOperator
and DAG
classes has changed. The change does not change the behavior of the method in either case.
For BaseOperator
Old signature:
def get_task_instances(self, session, start_date=None, end_date=None):
New signature:
@provide_session
def get_task_instances(self, start_date=None, end_date=None, session=None):
For DAG
Old signature:
def get_task_instances(
self, session, start_date=None, end_date=None, state=None):
New signature:
@provide_session
def get_task_instances(
self, start_date=None, end_date=None, state=None, session=None):
In either case, it is necessary to rewrite calls to the get_task_instances
method that currently provide the session
positional argument. New calls to this method look like:
# if you can rely on @provide_session
dag.get_task_instances()
# if you need to provide the session
dag.get_task_instances(session=your_session)
Airflow 1.10.3
New dag_discovery_safe_mode
config option
If dag_discovery_safe_mode
is enabled, only check files for DAGs if
they contain the strings "airflow" and "DAG". For backwards
compatibility, this option is enabled by default.
RedisPy dependency updated to v3 series
If you are using the Redis Sensor or Hook you may have to update your code. See redis-py porting instructions to check if your code might be affected (MSET, MSETNX, ZADD, and ZINCRBY all were, but read the full doc).
SLUGIFY_USES_TEXT_UNIDECODE or AIRFLOW_GPL_UNIDECODE no longer required
It is no longer required to set one of the environment variables to avoid a GPL dependency. Airflow will now always use text-unidecode if unidecode was not installed before.
new sync_parallelism
config option in celery section
The new sync_parallelism
config option will control how many processes CeleryExecutor will use to
fetch celery task state in parallel. Default value is max(1, number of cores - 1)
Rename of BashTaskRunner to StandardTaskRunner
BashTaskRunner has been renamed to StandardTaskRunner. It is the default task runner so you might need to update your config.
task_runner = StandardTaskRunner
Modification to config file discovery
If the AIRFLOW_CONFIG
environment variable was not set and the
~/airflow/airflow.cfg
file existed, airflow previously used
~/airflow/airflow.cfg
instead of $AIRFLOW_HOME/airflow.cfg
. Now airflow
will discover its config file using the $AIRFLOW_CONFIG
and $AIRFLOW_HOME
environment variables rather than checking for the presence of a file.
Changes in Google Cloud related operators
Most GCP-related operators have now optional PROJECT_ID
parameter. In case you do not specify it,
the project id configured in
GCP Connection is used.
There will be an AirflowException
thrown in case PROJECT_ID
parameter is not specified and the
connection used has no project id defined. This change should be backwards compatible as earlier version
of the operators had PROJECT_ID
mandatory.
Operators involved:
- GCP Compute Operators
- GceInstanceStartOperator
- GceInstanceStopOperator
- GceSetMachineTypeOperator
- GCP Function Operators
- GcfFunctionDeployOperator
- GCP Cloud SQL Operators
- CloudSqlInstanceCreateOperator
- CloudSqlInstancePatchOperator
- CloudSqlInstanceDeleteOperator
- CloudSqlInstanceDatabaseCreateOperator
- CloudSqlInstanceDatabasePatchOperator
- CloudSqlInstanceDatabaseDeleteOperator
Other GCP operators are unaffected.
Changes in Google Cloud related hooks
The change in GCP operators implies that GCP Hooks for those operators require now keyword parameters rather
than positional ones in all methods where project_id
is used. The methods throw an explanatory exception
in case they are called using positional parameters.
Hooks involved:
- GceHook
- GcfHook
- CloudSqlHook
Other GCP hooks are unaffected.
Changed behaviour of using default value when accessing variables
It's now possible to use None
as a default value with the default_var
parameter when getting a variable, e.g.
foo = Variable.get("foo", default_var=None)
if foo is None:
handle_missing_foo()
(Note: there is already Variable.setdefault()
which me be helpful in some cases.)
This changes the behaviour if you previously explicitly provided None
as a default value. If your code expects a KeyError
to be thrown, then don't pass the default_var
argument.
Removal of airflow_home
config setting
There were previously two ways of specifying the Airflow "home" directory
(~/airflow
by default): the AIRFLOW_HOME
environment variable, and the
airflow_home
config setting in the [core]
section.
If they had two different values different parts of the code base would end up
with different values. The config setting has been deprecated, and you should
remove the value from the config file and set AIRFLOW_HOME
environment
variable if you need to use a non default value for this.
(Since this setting is used to calculate what config file to load, it is not possible to keep just the config option)
Change of two methods signatures in GCPTransferServiceHook
The signature of the create_transfer_job
method in GCPTransferServiceHook
class has changed. The change does not change the behavior of the method.
Old signature:
def create_transfer_job(self, description, schedule, transfer_spec, project_id=None):
New signature:
def create_transfer_job(self, body):
It is necessary to rewrite calls to method. The new call looks like this:
body = {
'status': 'ENABLED',
'projectId': project_id,
'description': description,
'transferSpec': transfer_spec,
'schedule': schedule,
}
gct_hook.create_transfer_job(body)
The change results from the unification of all hooks and adjust to the official recommendations for the Google Cloud.
The signature of wait_for_transfer_job
method in GCPTransferServiceHook
has changed.
Old signature:
def wait_for_transfer_job(self, job):
New signature:
def wait_for_transfer_job(self, job, expected_statuses=(GcpTransferOperationStatus.SUCCESS, )):
The behavior of wait_for_transfer_job
has changed:
Old behavior:
wait_for_transfer_job
would wait for the SUCCESS status in specified jobs operations.
New behavior:
You can now specify an array of expected statuses. wait_for_transfer_job
now waits for any of them.
The default value of expected_statuses
is SUCCESS so that change is backwards compatible.
Moved two classes to different modules
The class GoogleCloudStorageToGoogleCloudStorageTransferOperator
has been moved from
airflow.contrib.operators.gcs_to_gcs_transfer_operator
to airflow.contrib.operators.gcp_transfer_operator
the class S3ToGoogleCloudStorageTransferOperator
has been moved from
airflow.contrib.operators.s3_to_gcs_transfer_operator
to airflow.contrib.operators.gcp_transfer_operator
The change was made to keep all the operators related to GCS Transfer Services in one file.
The previous imports will continue to work until Airflow 2.0
Fixed typo in --driver-class-path in SparkSubmitHook
The driver_classapth
argument to SparkSubmit Hook and Operator was
generating --driver-classpath
on the spark command line, but this isn't a
valid option to spark.
The argument has been renamed to driver_class_path
and the option it
generates has been fixed.
Airflow 1.10.2
New dag_processor_manager_log_location
config option
The DAG parsing manager log now by default will be log into a file, where its location is
controlled by the new dag_processor_manager_log_location
config option in core section.
DAG level Access Control for new RBAC UI
Extend and enhance new Airflow RBAC UI to support DAG level ACL. Each dag now has two permissions(one for write, one for read) associated('can_dag_edit', 'can_dag_read').
The admin will create new role, associate the dag permission with the target dag and assign that role to users. That user can only access / view the certain dags on the UI
that he has permissions on. If a new role wants to access all the dags, the admin could associate dag permissions on an artificial view(all_dags
) with that role.
We also provide a new cli command(sync_perm
) to allow admin to auto sync permissions.
Modification to ts_nodash
macro
ts_nodash
previously contained TimeZone information along with execution date. For Example: 20150101T000000+0000
. This is not user-friendly for file or folder names which was a popular use case for ts_nodash
. Hence this behavior has been changed and using ts_nodash
will no longer contain TimeZone information, restoring the pre-1.10 behavior of this macro. And a new macro ts_nodash_with_tz
has been added which can be used to get a string with execution date and timezone info without dashes.
Examples:
ts_nodash
:20150101T000000
ts_nodash_with_tz
:20150101T000000+0000
Semantics of next_ds/prev_ds changed for manually triggered runs
next_ds/prev_ds now map to execution_date instead of the next/previous schedule-aligned execution date for DAGs triggered in the UI.
User model changes
This patch changes the User.superuser
field from a hardcoded boolean to a Boolean()
database column. User.superuser
will default to False
, which means that this privilege will have to be granted manually to any users that may require it.
For example, open a Python shell and
from airflow import models, settings
session = settings.Session()
users = session.query(models.User).all() # [admin, regular_user]
users[1].superuser # False
admin = users[0]
admin.superuser = True
session.add(admin)
session.commit()
Custom auth backends interface change
We have updated the version of flask-login we depend upon, and as a result any
custom auth backends might need a small change: is_active
,
is_authenticated
, and is_anonymous
should now be properties. What this means is if
previously you had this in your user class
def is_active(self):
return self.active
then you need to change it like this
@property
def is_active(self):
return self.active
Support autodetected schemas to GoogleCloudStorageToBigQueryOperator
GoogleCloudStorageToBigQueryOperator is now support schema auto-detection is available when you load data into BigQuery. Unfortunately, changes can be required.
If BigQuery tables are created outside of airflow and the schema is not defined in the task, multiple options are available:
define a schema_fields:
gcs_to_bq.GoogleCloudStorageToBigQueryOperator(
...
schema_fields={...})
or define a schema_object:
gcs_to_bq.GoogleCloudStorageToBigQueryOperator(
...
schema_object='path/to/schema/object')
or enabled autodetect of schema:
gcs_to_bq.GoogleCloudStorageToBigQueryOperator(
...
autodetect=True)
Airflow 1.10.1
min_file_parsing_loop_time config option temporarily disabled
The scheduler.min_file_parsing_loop_time config option has been temporarily removed due to some bugs.
StatsD Metrics
The scheduler_heartbeat
metric has been changed from a gauge to a counter. Each loop of the scheduler will increment the counter by 1. This provides a higher degree of visibility and allows for better integration with Prometheus using the StatsD Exporter. The scheduler's activity status can be determined by graphing and alerting using a rate of change of the counter. If the scheduler goes down, the rate will drop to 0.
EMRHook now passes all of connection's extra to CreateJobFlow API
EMRHook.create_job_flow has been changed to pass all keys to the create_job_flow API, rather than just specific known keys for greater flexibility.
However prior to this release the "emr_default" sample connection that was created had invalid configuration, so creating EMR clusters might fail until your connection is updated. (Ec2KeyName, Ec2SubnetId, TerminationProtection and KeepJobFlowAliveWhenNoSteps were all top-level keys when they should be inside the "Instances" dict)
LDAP Auth Backend now requires TLS
Connecting to an LDAP server over plain text is not supported anymore. The
certificate presented by the LDAP server must be signed by a trusted
certificate, or you must provide the cacert
option under [ldap]
in the
config file.
If you want to use LDAP auth backend without TLS then you will have to create a custom-auth backend based on https://github.com/apache/airflow/blob/1.10.0/airflow/contrib/auth/backends/ldap_auth.py
Airflow 1.10
Installation and upgrading requires setting SLUGIFY_USES_TEXT_UNIDECODE=yes
in your environment or
AIRFLOW_GPL_UNIDECODE=yes
. In case of the latter a GPL runtime dependency will be installed due to a
dependency (python-nvd3 -> python-slugify -> unidecode).
Replace DataProcHook.await calls to DataProcHook.wait
The method name was changed to be compatible with the Python 3.7 async/await keywords
Setting UTF-8 as default mime_charset in email utils
Add a configuration variable(default_dag_run_display_number) to control numbers of dag run for display
Add a configuration variable(default_dag_run_display_number) under webserver section to control the number of dag runs to show in UI.
Default executor for SubDagOperator is changed to SequentialExecutor
New Webserver UI with Role-Based Access Control
The current webserver UI uses the Flask-Admin extension. The new webserver UI uses the Flask-AppBuilder (FAB) extension. FAB has built-in authentication support and Role-Based Access Control (RBAC), which provides configurable roles and permissions for individual users.
To turn on this feature, in your airflow.cfg file (under [webserver]), set the configuration variable rbac = True
, and then run airflow
command, which will generate the webserver_config.py
file in your $AIRFLOW_HOME.
Setting up Authentication
FAB has built-in authentication support for DB, OAuth, OpenID, LDAP, and REMOTE_USER. The default auth type is AUTH_DB
.
For any other authentication type (OAuth, OpenID, LDAP, REMOTE_USER), see the Authentication section of FAB docs for how to configure variables in webserver_config.py file.
Once you modify your config file, run airflow db init
to generate new tables for RBAC support (these tables will have the prefix ab_
).
Creating an Admin Account
Once configuration settings have been updated and new tables have been generated, create an admin account with airflow create_user
command.
Using your new UI
Run airflow webserver
to start the new UI. This will bring up a log in page, enter the recently created admin username and password.
There are five roles created for Airflow by default: Admin, User, Op, Viewer, and Public. To configure roles/permissions, go to the Security
tab and click List Roles
in the new UI.
Breaking changes
- AWS Batch Operator renamed property queue to job_queue to prevent conflict with the internal queue from CeleryExecutor - AIRFLOW-2542
- Users created and stored in the old users table will not be migrated automatically. FAB's built-in authentication support must be reconfigured.
- Airflow dag home page is now
/home
(instead of/admin
). - All ModelViews in Flask-AppBuilder follow a different pattern from Flask-Admin. The
/admin
part of the URL path will no longer exist. For example:/admin/connection
becomes/connection/list
,/admin/connection/new
becomes/connection/add
,/admin/connection/edit
becomes/connection/edit
, etc. - Due to security concerns, the new webserver will no longer support the features in the
Data Profiling
menu of old UI, includingAd Hoc Query
,Charts
, andKnown Events
. - HiveServer2Hook.get_results() always returns a list of tuples, even when a single column is queried, as per Python API 2.
- UTC is now the default timezone: Either reconfigure your workflows scheduling in UTC or set
default_timezone
as explained in https://airflow.apache.org/timezone.html#default-time-zone
airflow.contrib.sensors.hdfs_sensors renamed to airflow.contrib.sensors.hdfs_sensor
We now rename airflow.contrib.sensors.hdfs_sensors to airflow.contrib.sensors.hdfs_sensor for consistency purpose.
MySQL setting required
We now rely on more strict ANSI SQL settings for MySQL in order to have sane defaults. Make sure
to have specified explicit_defaults_for_timestamp=1
in your my.cnf under [mysqld]
Celery config
To make the config of Airflow compatible with Celery, some properties have been renamed:
celeryd_concurrency -> worker_concurrency
celery_result_backend -> result_backend
celery_ssl_active -> ssl_active
celery_ssl_cert -> ssl_cert
celery_ssl_key -> ssl_key
Resulting in the same config parameters as Celery 4, with more transparency.
GCP Dataflow Operators
Dataflow job labeling is now supported in Dataflow{Java,Python}Operator with a default "airflow-version" label, please upgrade your google-cloud-dataflow or apache-beam version to 2.2.0 or greater.
BigQuery Hooks and Operator
The bql
parameter passed to BigQueryOperator
and BigQueryBaseCursor.run_query
has been deprecated and renamed to sql
for consistency purposes. Using bql
will still work (and raise a DeprecationWarning
), but is no longer
supported and will be removed entirely in Airflow 2.0
Redshift to S3 Operator
With Airflow 1.9 or lower, Unload operation always included header row. In order to include header row,
we need to turn off parallel unload. It is preferred to perform unload operation using all nodes so that it is
faster for larger tables. So, parameter called include_header
is added and default is set to False.
Header row will be added only if this parameter is set True and also in that case parallel will be automatically turned off (PARALLEL OFF
)
Google cloud connection string
With Airflow 1.9 or lower, there were two connection strings for the Google Cloud operators, both google_cloud_storage_default
and google_cloud_default
. This can be confusing and therefore the google_cloud_storage_default
connection id has been replaced with google_cloud_default
to make the connection id consistent across Airflow.
Logging Configuration
With Airflow 1.9 or lower, FILENAME_TEMPLATE
, PROCESSOR_FILENAME_TEMPLATE
, LOG_ID_TEMPLATE
, END_OF_LOG_MARK
were configured in airflow_local_settings.py
. These have been moved into the configuration file, and hence if you were using a custom configuration file the following defaults need to be added.
[core]
fab_logging_level = WARN
log_filename_template = {{{{ ti.dag_id }}}}/{{{{ ti.task_id }}}}/{{{{ ts }}}}/{{{{ try_number }}}}.log
log_processor_filename_template = {{{{ filename }}}}.log
[elasticsearch]
elasticsearch_log_id_template = {{dag_id}}-{{task_id}}-{{execution_date}}-{{try_number}}
elasticsearch_end_of_log_mark = end_of_log
The previous setting of log_task_reader
is not needed in many cases now when using the default logging config with remote storages. (Previously it needed to be set to s3.task
or similar. This is not needed with the default config anymore)
Change of per-task log path
With the change to Airflow core to be timezone aware the default log path for task instances will now include timezone information. This will by default mean all previous task logs won't be found. You can get the old behaviour back by setting the following config options:
[core]
log_filename_template = {{ ti.dag_id }}/{{ ti.task_id }}/{{ execution_date.strftime("%%Y-%%m-%%dT%%H:%%M:%%S") }}/{{ try_number }}.log
Airflow 1.9
SSH Hook updates, along with new SSH Operator & SFTP Operator
SSH Hook now uses the Paramiko library to create an ssh client connection, instead of the sub-process based ssh command execution previously (<1.9.0), so this is backward incompatible.
- update SSHHook constructor
- use SSHOperator class in place of SSHExecuteOperator which is removed now. Refer to test_ssh_operator.py for usage info.
- SFTPOperator is added to perform secure file transfer from serverA to serverB. Refer to test_sftp_operator.py for usage info.
- No updates are required if you are using ftpHook, it will continue to work as is.
S3Hook switched to use Boto3
The airflow.hooks.S3_hook.S3Hook has been switched to use boto3 instead of the older boto (a.k.a. boto2). This results in a few backwards incompatible changes to the following classes: S3Hook:
- the constructors no longer accepts
s3_conn_id
. It is now calledaws_conn_id
. - the default connection is now "aws_default" instead of "s3_default"
- the return type of objects returned by
get_bucket
is now boto3.s3.Bucket - the return type of
get_key
, andget_wildcard_key
is now an boto3.S3.Object.
If you are using any of these in your DAGs and specify a connection ID you will need to update the parameter name for the connection to "aws_conn_id": S3ToHiveTransfer, S3PrefixSensor, S3KeySensor, RedshiftToS3Transfer.
Logging update
The logging structure of Airflow has been rewritten to make configuration easier and the logging system more transparent.
A quick recap about logging
A logger is the entry point into the logging system. Each logger is a named bucket to which messages can be written for processing. A logger is configured to have a log level. This log level describes the severity of the messages that the logger will handle. Python defines the following log levels: DEBUG, INFO, WARNING, ERROR or CRITICAL.
Each message that is written to the logger is a Log Record. Each log record contains a log level indicating the severity of that specific message. A log record can also contain useful metadata that describes the event that is being logged. This can include details such as a stack trace or an error code.
When a message is given to the logger, the log level of the message is compared to the log level of the logger. If the log level of the message meets or exceeds the log level of the logger itself, the message will undergo further processing. If it doesn’t, the message will be ignored.
Once a logger has determined that a message needs to be processed, it is passed to a Handler. This configuration is now more flexible and can be easily be maintained in a single file.
Changes in Airflow Logging
Airflow's logging mechanism has been refactored to use Python’s built-in logging
module to perform logging of the application. By extending classes with the existing LoggingMixin
, all the logging will go through a central logger. Also the BaseHook
and BaseOperator
already extend this class, so it is easily available to do logging.
The main benefit is easier configuration of the logging by setting a single centralized python file. Disclaimer; there is still some inline configuration, but this will be removed eventually. The new logging class is defined by setting the dotted classpath in your ~/airflow/airflow.cfg
file:
# Logging class
# Specify the class that will specify the logging configuration
# This class has to be on the python classpath
logging_config_class = my.path.default_local_settings.LOGGING_CONFIG
The logging configuration file needs to be on the PYTHONPATH
, for example $AIRFLOW_HOME/config
. This directory is loaded by default. Any directory may be added to the PYTHONPATH
, this might be handy when the config is in another directory or a volume is mounted in case of Docker.
The config can be taken from airflow/config_templates/airflow_local_settings.py
as a starting point. Copy the contents to ${AIRFLOW_HOME}/config/airflow_local_settings.py
, and alter the config as is preferred.

To customize the logging (for example, use logging rotate), define one or more of the logging handles that Python has to offer. For more details about the Python logging, please refer to the official logging documentation.
Furthermore, this change also simplifies logging within the DAG itself:

Template path of the file_task_handler
The file_task_handler
logger has been made more flexible. The default format can be changed, {dag_id}/{task_id}/{execution_date}/{try_number}.log
by supplying Jinja templating in the FILENAME_TEMPLATE
configuration variable. See the file_task_handler
for more information.
I'm using S3Log or GCSLogs, what do I do!?
If you are logging to Google cloud storage, please see the Google cloud platform documentation for logging instructions.
If you are using S3, the instructions should be largely the same as the Google cloud platform instructions above. You will need a custom logging config. The REMOTE_BASE_LOG_FOLDER
configuration key in your airflow config has been removed, therefore you will need to take the following steps:
- Copy the logging configuration from
airflow/config_templates/airflow_logging_settings.py
. - Place it in a directory inside the Python import path
PYTHONPATH
. If you are using Python 2.7, ensuring that any__init__.py
files exist so that it is importable. - Update the config by setting the path of
REMOTE_BASE_LOG_FOLDER
explicitly in the config. TheREMOTE_BASE_LOG_FOLDER
key is not used anymore. - Set the
logging_config_class
to the filename and dict. For example, if you placecustom_logging_config.py
on the base of yourPYTHONPATH
, you will need to setlogging_config_class = custom_logging_config.LOGGING_CONFIG
in your config as Airflow 1.8.
New Features
Dask Executor
A new DaskExecutor allows Airflow tasks to be run in Dask Distributed clusters.
Deprecated Features
These features are marked for deprecation. They may still work (and raise a DeprecationWarning
), but are no longer
supported and will be removed entirely in Airflow 2.0
-
If you're using the
google_cloud_conn_id
ordataproc_cluster
argument names explicitly incontrib.operators.Dataproc{*}Operator
(s), be sure to rename them togcp_conn_id
orcluster_name
, respectively. We've renamed these arguments for consistency. (AIRFLOW-1323) -
post_execute()
hooks now take two arguments,context
andresult
(AIRFLOW-886)Previously, post_execute() only took one argument,
context
. -
contrib.hooks.gcp_dataflow_hook.DataFlowHook
starts to use--runner=DataflowRunner
instead ofDataflowPipelineRunner
, which is removed from the packagegoogle-cloud-dataflow-0.6.0
. -
The pickle type for XCom messages has been replaced by json to prevent RCE attacks. Note that JSON serialization is stricter than pickling, so if you want to e.g. pass raw bytes through XCom you must encode them using an encoding like base64. By default pickling is still enabled until Airflow 2.0. To disable it set enable_xcom_pickling = False in your Airflow config.
Airflow 1.8.1
The Airflow package name was changed from airflow
to apache-airflow
during this release. You must uninstall
a previously installed version of Airflow before installing 1.8.1.
Airflow 1.8
Database
The database schema needs to be upgraded. Make sure to shutdown Airflow and make a backup of your database. To
upgrade the schema issue airflow upgradedb
.
Upgrade systemd unit files
Systemd unit files have been updated. If you use systemd please make sure to update these.
Please note that the webserver does not detach properly, this will be fixed in a future version.
Tasks not starting although dependencies are met due to stricter pool checking
Airflow 1.7.1 has issues with being able to over subscribe to a pool, ie. more slots could be used than were available. This is fixed in Airflow 1.8.0, but due to past issue jobs may fail to start although their dependencies are met after an upgrade. To workaround either temporarily increase the amount of slots above the amount of queued tasks or use a new pool.
Less forgiving scheduler on dynamic start_date
Using a dynamic start_date (e.g. start_date = datetime.now()
) is not considered a best practice. The 1.8.0 scheduler
is less forgiving in this area. If you encounter DAGs not being scheduled you can try using a fixed start_date and
renaming your DAG. The last step is required to make sure you start with a clean slate, otherwise the old schedule can
interfere.
New and updated scheduler options
Please read through the new scheduler options, defaults have changed since 1.7.1.
child_process_log_directory
In order to increase the robustness of the scheduler, DAGS are now processed in their own process. Therefore each
DAG has its own log file for the scheduler. These log files are placed in child_process_log_directory
which defaults to
<AIRFLOW_HOME>/scheduler/latest
. You will need to make sure these log files are removed.
DAG logs or processor logs ignore and command line settings for log file locations.
run_duration
Previously the command line option num_runs
was used to let the scheduler terminate after a certain amount of
loops. This is now time bound and defaults to -1
, which means run continuously. See also num_runs.
num_runs
Previously num_runs
was used to let the scheduler terminate after a certain amount of loops. Now num_runs specifies
the number of times to try to schedule each DAG file within run_duration
time. Defaults to -1
, which means try
indefinitely. This is only available on the command line.
min_file_process_interval
After how much time should an updated DAG be picked up from the filesystem.
min_file_parsing_loop_time
CURRENTLY DISABLED DUE TO A BUG How many seconds to wait between file-parsing loops to prevent the logs from being spammed.
dag_dir_list_interval
The frequency with which the scheduler should relist the contents of the DAG directory. If while developing +dags, they are not being picked up, have a look at this number and decrease it when necessary.
catchup_by_default
By default the scheduler will fill any missing interval DAG Runs between the last execution date and the current date.
This setting changes that behavior to only execute the latest interval. This can also be specified per DAG as
catchup = False / True
. Command line backfills will still work.
Faulty DAGs do not show an error in the Web UI
Due to changes in the way Airflow processes DAGs the Web UI does not show an error when processing a faulty DAG. To
find processing errors go the child_process_log_directory
which defaults to <AIRFLOW_HOME>/scheduler/latest
.
New DAGs are paused by default
Previously, new DAGs would be scheduled immediately. To retain the old behavior, add this to airflow.cfg:
[core]
dags_are_paused_at_creation = False
Airflow Context variable are passed to Hive config if conf is specified
If you specify a hive conf to the run_cli command of the HiveHook, Airflow add some
convenience variables to the config. In case you run a secure Hadoop setup it might be
required to allow these variables by adjusting you hive configuration to add airflow\.ctx\..*
to the regex
of user-editable configuration properties. See
the Hive docs on Configuration Properties for more info.
Google Cloud Operator and Hook alignment
All Google Cloud Operators and Hooks are aligned and use the same client library. Now you have a single connection type for all kinds of Google Cloud Operators.
If you experience problems connecting with your operator make sure you set the connection type "Google Cloud".
Also the old P12 key file type is not supported anymore and only the new JSON key files are supported as a service account.
Deprecated Features
These features are marked for deprecation. They may still work (and raise a DeprecationWarning
), but are no longer
supported and will be removed entirely in Airflow 2.0
-
Hooks and operators must be imported from their respective submodules
airflow.operators.PigOperator
is no longer supported;from airflow.operators.pig_operator import PigOperator
is. (AIRFLOW-31, AIRFLOW-200) -
Operators no longer accept arbitrary arguments
Previously,
Operator.__init__()
accepted any arguments (either positional*args
or keyword**kwargs
) without complaint. Now, invalid arguments will be rejected. (https://github.com/apache/airflow/pull/1285) -
The config value secure_mode will default to True which will disable some insecure endpoints/features
Known Issues
There is a report that the default of "-1" for num_runs creates an issue where errors are reported while parsing tasks.
It was not confirmed, but a workaround was found by changing the default back to None
.
To do this edit cli.py
, find the following:
'num_runs': Arg(
("-n", "--num_runs"),
default=-1, type=int,
help="Set the number of runs to execute before exiting"),
and change default=-1
to default=None
. If you have this issue please report it on the mailing list.
Airflow 1.7.1.2
Changes to Configuration
Email configuration change
To continue using the default smtp email backend, change the email_backend line in your config file from:
[email]
email_backend = airflow.utils.send_email_smtp
to:
[email]
email_backend = airflow.utils.email.send_email_smtp
S3 configuration change
To continue using S3 logging, update your config file so:
s3_log_folder = s3://my-airflow-log-bucket/logs
becomes:
remote_base_log_folder = s3://my-airflow-log-bucket/logs
remote_log_conn_id = <your desired s3 connection>
