Azure Service Bus client library for Python

Azure Service Bus is a high performance cloud-managed messaging service for providing real-time and fault-tolerant communication between distributed senders and receivers.

Service Bus provides multiple mechanisms for asynchronous highly reliable communication, such as structured first-in-first-out messaging, publish/subscribe capabilities, and the ability to easily scale as your needs grow.

Use the Service Bus client library for Python to communicate between applications and services and implement asynchronous messaging patterns.

• Create Service Bus namespaces, queues, topics, and subscriptions, and modify their settings.
• Send and receive messages within your Service Bus channels.
• Utilize message locks, sessions, and dead letter functionality to implement complex messaging patterns.

NOTE: If you are using version 0.50 or lower and want to migrate to the latest version of this package please look at our migration guide to move from Service Bus V0.50 to Service Bus V7.

Getting started

Install the package

Install the Azure Service Bus client library for Python with pip:

pip install azure-servicebus

Prerequisites:

To use this package, you must have:

• Azure subscription - Create a free account
• Azure Service Bus - Namespace and management credentials
• Python 3.8 or later - Install Python

If you need an Azure service bus namespace, you can create it via the Azure Portal. If you do not wish to use the graphical portal UI, you can use the Azure CLI via Cloud Shell, or Azure CLI run locally, to create one with this Azure CLI command:

az servicebus namespace create --resource-group <resource-group-name> --name <servicebus-namespace-name> --location <servicebus-namespace-location>

Authenticate the client

Interaction with Service Bus starts with an instance of the ServiceBusClient class. You either need a connection string with SAS key, or a namespace and one of its account keys to instantiate the client object. Please find the samples linked below for demonstration as to how to authenticate via either approach.

Create client from connection string

• To obtain the required credentials, one can use the Azure CLI snippet (Formatted for Bash Shell) at the top of the linked sample to populate an environment variable with the service bus connection string (you can also find these values in the Azure Portal by following the step-by-step guide to Get a service bus connection string).

Create client using the azure-identity library:

• This constructor takes the fully qualified namespace of your Service Bus instance and a credential that implements the TokenCredential protocol. There are implementations of the TokenCredential protocol available in the azure-identity package. The fully qualified namespace is of the format <yournamespace.servicebus.windows.net>.
• To use the credential types provided by azure-identity, please install the package: pip install azure-identity
• Additionally, to use the async API, you must first install an async transport, such as aiohttp: pip install aiohttp
• When using Azure Active Directory, your principal must be assigned a role which allows access to Service Bus, such as the Azure Service Bus Data Owner role. For more information about using Azure Active Directory authorization with Service Bus, please refer to the associated documentation.

Note: client can be initialized without a context manager, but must be manually closed via client.close() to not leak resources.

Key concepts

Once you've initialized a ServiceBusClient, you can interact with the primary resource types within a Service Bus Namespace, of which multiple can exist and on which actual message transmission takes place, the namespace often serving as an application container:

• Queue: Allows for Sending and Receiving of message. Often used for point-to-point communication.

• Topic: As opposed to Queues, Topics are better suited to publish/subscribe scenarios. A topic can be sent to, but requires a subscription, of which there can be multiple in parallel, to consume from.

• Subscription: The mechanism to consume from a Topic. Each subscription is independent, and receives a copy of each message sent to the topic. Rules and Filters can be used to tailor which messages are received by a specific subscription.

For more information about these resources, see What is Azure Service Bus?.

To interact with these resources, one should be familiar with the following SDK concepts:

• ServiceBusClient: This is the object a user should first initialize to connect to a Service Bus Namespace. To interact with a queue, topic, or subscription, one would spawn a sender or receiver off of this client.

• ServiceBusSender: To send messages to a Queue or Topic, one would use the corresponding get_queue_sender or get_topic_sender method off of a ServiceBusClient instance as seen here.

• ServiceBusReceiver: To receive messages from a Queue or Subscription, one would use the corresponding get_queue_receiver or get_subscription_receiver method off of a ServiceBusClient instance as seen here.

• ServiceBusMessage: When sending, this is the type you will construct to contain your payload. When receiving, this is where you will access the payload.

Thread safety

We do not guarantee that the ServiceBusClient, ServiceBusSender, and ServiceBusReceiver are thread-safe. We do not recommend reusing these instances across threads. It is up to the running application to use these classes in a thread-safe manner.

Examples

The following sections provide several code snippets covering some of the most common Service Bus tasks, including:

• Send messages to a queue
• Receive messages from a queue
• Send and receive a message from a session enabled queue
• Working with topics and subscriptions
• Settle a message after receipt
• Automatically renew Message or Session locks

To perform management tasks such as creating and deleting queues/topics/subscriptions, please utilize the azure-mgmt-servicebus library, available here.

Please find further examples in the samples directory demonstrating common Service Bus scenarios such as sending, receiving, session management and message handling.

Send messages to a queue

NOTE: see reference documentation here.

This example sends single message and array of messages to a queue that is assumed to already exist, created via the Azure portal or az commands.

from azure.servicebus import ServiceBusClient, ServiceBusMessage
from azure.identity import DefaultAzureCredential

import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_sender(queue_name) as sender:
        # Sending a single message
        single_message = ServiceBusMessage("Single message")
        sender.send_messages(single_message)

        # Sending a list of messages
        messages = [ServiceBusMessage("First message"), ServiceBusMessage("Second message")]
        sender.send_messages(messages)

NOTE: A message may be scheduled for delayed delivery using the ServiceBusSender.schedule_messages() method, or by specifying ServiceBusMessage.scheduled_enqueue_time_utc before calling ServiceBusSender.send_messages()

For more detail on scheduling and schedule cancellation please see a sample here.

Receive messages from a queue

To receive from a queue, you can either perform an ad-hoc receive via receiver.receive_messages() or receive persistently through the receiver itself.

Receive messages from a queue through iterating over ServiceBusReceiver

from azure.servicebus import ServiceBusClient
from azure.identity import DefaultAzureCredential

import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    # max_wait_time specifies how long the receiver should wait with no incoming messages before stopping receipt.
    # Default is None; to receive forever.
    with client.get_queue_receiver(queue_name, max_wait_time=30) as receiver:
        for msg in receiver:  # ServiceBusReceiver instance is a generator.
            print(str(msg))
            # If it is desired to halt receiving early, one can break out of the loop here safely.

NOTE: Any message received with receive_mode=PEEK_LOCK (this is the default, with the alternative RECEIVE_AND_DELETE removing the message from the queue immediately on receipt) has a lock that must be renewed via receiver.renew_message_lock before it expires if processing would take longer than the lock duration. See AutoLockRenewer for a helper to perform this in the background automatically. Lock duration is set in Azure on the queue or topic itself.

Receive messages from a queue through ServiceBusReceiver.receive_messages()

NOTE: ServiceBusReceiver.receive_messages() receives a single or constrained list of messages through an ad-hoc method call, as opposed to receiving perpetually from the generator. It always returns a list.

from azure.servicebus import ServiceBusClient
from azure.identity import DefaultAzureCredential

import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(queue_name) as receiver:
        received_message_array = receiver.receive_messages(max_wait_time=10)  # try to receive a single message within 10 seconds
        if received_message_array:
            print(str(received_message_array[0]))

    with client.get_queue_receiver(queue_name) as receiver:
        received_message_array = receiver.receive_messages(max_message_count=5, max_wait_time=10)  # try to receive maximum 5 messages in a batch within 10 seconds
        for message in received_message_array:
            print(str(message))

In this example, max_message_count declares the maximum number of messages to attempt receiving before hitting a max_wait_time as specified in seconds.

NOTE: It should also be noted that ServiceBusReceiver.peek_messages() is subtly different than receiving, as it does not lock the messages being peeked, and thus they cannot be settled.

Send and receive a message from a session enabled queue

NOTE: see reference documentation for session send and receive.

Sessions provide first-in-first-out and single-receiver semantics on top of a queue or subscription. While the actual receive syntax is the same, initialization differs slightly.

from azure.servicebus import ServiceBusClient, ServiceBusMessage
from azure.identity import DefaultAzureCredential

import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_SESSION_QUEUE_NAME']
session_id = os.environ['SERVICE_BUS_SESSION_ID']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_sender(queue_name) as sender:
        sender.send_messages(ServiceBusMessage("Session Enabled Message", session_id=session_id))

    # If session_id is null here, will receive from the first available session.
    with client.get_queue_receiver(queue_name, session_id=session_id) as receiver:
        for msg in receiver:
            print(str(msg))

NOTE: Messages received from a session do not need their locks renewed like a non-session receiver; instead the lock management occurs at the session level with a session lock that may be renewed with receiver.session.renew_lock()

Working with topics and subscriptions

NOTE: see reference documentation for topics and subscriptions.

Topics and subscriptions give an alternative to queues for sending and receiving messages. See documents here for more overarching detail, and of how these differ from queues.

from azure.servicebus import ServiceBusClient, ServiceBusMessage
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
topic_name = os.environ['SERVICE_BUS_TOPIC_NAME']
subscription_name = os.environ['SERVICE_BUS_SUBSCRIPTION_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_topic_sender(topic_name) as sender:
        sender.send_messages(ServiceBusMessage("Data"))

    # If session_id is null here, will receive from the first available session.
    with client.get_subscription_receiver(topic_name, subscription_name) as receiver:
        for msg in receiver:
            print(str(msg))

Settle a message after receipt

When receiving from a queue, you have multiple actions you can take on the messages you receive.

NOTE: You can only settle ServiceBusReceivedMessage objects which are received in ServiceBusReceiveMode.PEEK_LOCK mode (this is the default). ServiceBusReceiveMode.RECEIVE_AND_DELETE mode removes the message from the queue on receipt. ServiceBusReceivedMessage messages returned from peek_messages() cannot be settled, as the message lock is not taken like it is in the aforementioned receive methods.

If the message has a lock as mentioned above, settlement will fail if the message lock has expired. If processing would take longer than the lock duration, it must be maintained via receiver.renew_message_lock before it expires. Lock duration is set in Azure on the queue or topic itself. See AutoLockRenewer for a helper to perform this in the background automatically.

Complete

Declares the message processing to be successfully completed, removing the message from the queue.

from azure.servicebus import ServiceBusClient
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(queue_name) as receiver:
        for msg in receiver:
            print(str(msg))
            receiver.complete_message(msg)

Abandon

Abandon processing of the message for the time being, returning the message immediately back to the queue to be picked up by another (or the same) receiver.

from azure.servicebus import ServiceBusClient
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(queue_name) as receiver:
        for msg in receiver:
            print(str(msg))
            receiver.abandon_message(msg)

DeadLetter

Transfer the message from the primary queue into a special "dead-letter sub-queue" where it can be accessed using the ServiceBusClient.get_<queue|subscription>_receiver function with parameter sub_queue=ServiceBusSubQueue.DEAD_LETTER and consumed from like any other receiver. (see sample here)

from azure.servicebus import ServiceBusClient
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(queue_name) as receiver:
        for msg in receiver:
            print(str(msg))
            receiver.dead_letter_message(msg)

Defer

Defer is subtly different from the prior settlement methods. It prevents the message from being directly received from the queue by setting it aside such that it must be received by sequence number in a call to ServiceBusReceiver.receive_deferred_messages (see sample here)

from azure.servicebus import ServiceBusClient
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(queue_name) as receiver:
        for msg in receiver:
            print(str(msg))
            receiver.defer_message(msg)

Automatically renew Message or Session locks

NOTE: see reference documentation for auto-lock-renewal.

AutoLockRenewer is a simple method for ensuring your message or session remains locked even over long periods of time, if calling receiver.renew_message_lock/receiver.session.renew_lock is impractical or undesired. Internally, it is not much more than shorthand for creating a concurrent watchdog to do lock renewal if the object is nearing expiry. It should be used as follows:

• Message lock automatic renewing

from azure.servicebus import ServiceBusClient, AutoLockRenewer
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
queue_name = os.environ['SERVICE_BUS_QUEUE_NAME']

# Can also be called via "with AutoLockRenewer() as renewer" to automate closing.
renewer = AutoLockRenewer()
credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(queue_name) as receiver:
        for msg in receiver.receive_messages():
            renewer.register(receiver, msg, max_lock_renewal_duration=60)
            # Do your application logic here
            receiver.complete_message(msg)
renewer.close()

• Session lock automatic renewing

from azure.servicebus import ServiceBusClient, AutoLockRenewer
from azure.identity import DefaultAzureCredential


import os
fully_qualified_namespace = os.environ['SERVICEBUS_FULLY_QUALIFIED_NAMESPACE']
session_queue_name = os.environ['SERVICE_BUS_SESSION_QUEUE_NAME']
session_id = os.environ['SERVICE_BUS_SESSION_ID']

# Can also be called via "with AutoLockRenewer() as renewer" to automate closing.
renewer = AutoLockRenewer()
credential = DefaultAzureCredential()
with ServiceBusClient(fully_qualified_namespace, credential) as client:
    with client.get_queue_receiver(session_queue_name, session_id=session_id) as receiver:
        renewer.register(receiver, receiver.session, max_lock_renewal_duration=300) # Duration for how long to maintain the lock for, in seconds.

        for msg in receiver.receive_messages():
            # Do your application logic here
            receiver.complete_message(msg)
renewer.close()

If for any reason auto-renewal has been interrupted or failed, this can be observed via the auto_renew_error property on the object being renewed, or by having passed a callback to the on_lock_renew_failure parameter on renewer initialization. It would also manifest when trying to take action (such as completing a message) on the specified object.

Troubleshooting

Logging

• Enable azure.servicebus logger to collect traces from the library.
• Enable AMQP frame level trace by setting logging_enable=True when creating the client.

import logging
import sys

handler = logging.StreamHandler(stream=sys.stdout)
log_fmt = logging.Formatter(fmt="%(asctime)s | %(threadName)s | %(levelname)s | %(name)s | %(message)s")
handler.setFormatter(log_fmt)
logger = logging.getLogger('azure.servicebus')
logger.setLevel(logging.DEBUG)
logger.addHandler(handler)

...

from azure.servicebus import ServiceBusClient

client = ServiceBusClient(..., logging_enable=True)

Timeouts

There are various timeouts a user should be aware of within the library.

• 10 minute service side link closure: A link, once opened, will be closed after 10 minutes idle to protect the service against resource leakage. This should largely be transparent to a user, but if you notice a reconnect occurring after such a duration, this is why. Performing any operations, including management operations, on the link will extend this timeout.
• max_wait_time: Provided on creation of a receiver or when calling receive_messages(), the time after which receiving messages will halt after no traffic. This applies both to the imperative receive_messages() function as well as the length a generator-style receive will run for before exiting if there are no messages. Passing None (default) will wait forever, up until the 10 minute threshold if no other action is taken.

NOTE: If processing of a message or session is sufficiently long as to cause timeouts, as an alternative to calling receiver.renew_message_lock/receiver.session.renew_lock manually, one can leverage the AutoLockRenewer functionality detailed above.

Common Exceptions

The Service Bus APIs generate the following exceptions in azure.servicebus.exceptions:

• ServiceBusConnectionError: An error occurred in the connection to the service. This may have been caused by a transient network issue or service problem. It is recommended to retry.
• ServiceBusAuthorizationError: An error occurred when authorizing the connection to the service. This may have been caused by the credentials not having the right permission to perform the operation. It is recommended to check the permission of the credentials.
• ServiceBusAuthenticationError: An error occurred when authenticate the connection to the service. This may have been caused by the credentials being incorrect. It is recommended to check the credentials.
• OperationTimeoutError: This indicates that the service did not respond to an operation within the expected amount of time. This may have been caused by a transient network issue or service problem. The service may or may not have successfully completed the request; the status is not known. It is recommended to attempt to verify the current state and retry if necessary.
• MessageSizeExceededError: This indicate that the message content is larger than the service bus frame size. This could happen when too many service bus messages are sent in a batch or the content passed into the body of a Message is too large. It is recommended to reduce the count of messages being sent in a batch or the size of content being passed into a single ServiceBusMessage.
• MessageAlreadySettled: This indicates failure to settle the message. This could happen when trying to settle an already-settled message.
• MessageLockLostError: The lock on the message has expired and it has been released back to the queue. It will need to be received again in order to settle it. You should be aware of the lock duration of a message and keep renewing the lock before expiration in case of long processing time. AutoLockRenewer could help on keeping the lock of the message automatically renewed.
• SessionLockLostError: The lock on the session has expired. All unsettled messages that have been received can no longer be settled. It is recommended to reconnect to the session if receive messages again if necessary. You should be aware of the lock duration of a session and keep renewing the lock before expiration in case of long processing time. AutoLockRenewer could help on keeping the lock of the session automatically renewed.
• MessageNotFoundError: Attempt to receive a message with a particular sequence number. This message isn't found. Make sure the message hasn't been received already. Check the deadletter queue to see if the message has been deadlettered.
• MessagingEntityNotFoundError: Entity associated with the operation doesn't exist or it has been deleted. Please make sure the entity exists.
• MessagingEntityDisabledError: Request for a runtime operation on a disabled entity. Please Activate the entity.
• ServiceBusQuotaExceededError: The messaging entity has reached its maximum allowable size, or the maximum number of connections to a namespace has been exceeded. Create space in the entity by receiving messages from the entity or its subqueues.
• ServiceBusServerBusyError: Service isn't able to process the request at this time. Client can wait for a period of time, then retry the operation.
• ServiceBusCommunicationError: Client isn't able to establish a connection to Service Bus. Make sure the supplied host name is correct and the host is reachable. If your code runs in an environment with a firewall/proxy, ensure that the traffic to the Service Bus domain/IP address and ports isn't blocked.
• SessionCannotBeLockedError: Attempt to connect to a session with a specific session ID, but the session is currently locked by another client. Make sure the session is unlocked by other clients.
• AutoLockRenewFailed: An attempt to renew a lock on a message or session in the background has failed. This could happen when the receiver used by AutoLockRenewer is closed or the lock of the renewable has expired. It is recommended to re-register the renewable message or session by receiving the message or connect to the sessionful entity again.
• AutoLockRenewTimeout: The time allocated to renew the message or session lock has elapsed. You could re-register the object that wants be auto lock renewed or extend the timeout in advance.
• ServiceBusError: All other Service Bus related errors. It is the root error class of all the errors described above.

Please view the exceptions reference docs for detailed descriptions of our common Exception types.

Pure Python AMQP Transport and Backward Compatibility Support

The Azure Service Bus client library is now based on a pure Python AMQP implementation. uAMQP has been removed as required dependency.

To use uAMQP as the underlying transport:

1. Install uamqp with pip.

$ pip install uamqp

2. Pass uamqp_transport=True during client construction.

from azure.servicebus import ServiceBusClient
connection_str = '<< CONNECTION STRING FOR THE SERVICE BUS NAMESPACE >>'
queue_name = '<< NAME OF THE QUEUE >>'
client = ServiceBusClient.from_connection_string(
    connection_str, uamqp_transport=True
)

Note: The message attribute on ServiceBusMessage/ServiceBusMessageBatch/ServiceBusReceivedMessage, which previously exposed the uamqp.Message, has been deprecated. The "Legacy" objects returned by message attribute have been introduced to help facilitate the transition.

To enable the uamqp logger to collect traces from the underlying uAMQP library:

import logging

uamqp_logger = logging.getLogger('uamqp')
uamqp_logger.setLevel(logging.DEBUG)
uamqp_logger.addHandler(handler)

...

from azure.servicebus import ServiceBusClient

client = ServiceBusClient(..., logging_enable=True)

There may be cases where you consider the uamqp logging to be too verbose. To suppress unnecessary logging, add the following snippet to the top of your code:

import logging

# The logging levels below may need to be changed based on the logging that you want to suppress.
uamqp_logger = logging.getLogger('uamqp')
uamqp_logger.setLevel(logging.ERROR)

# or even further fine-grained control, suppressing the warnings in uamqp.connection module
uamqp_connection_logger = logging.getLogger('uamqp.connection')
uamqp_connection_logger.setLevel(logging.ERROR)

Building uAMQP wheel from source

azure-servicebus depends on the uAMQP for the AMQP protocol implementation. uAMQP wheels are provided for most major operating systems and will be installed automatically when installing azure-servicebus. If uAMQP is intended to be used as the underlying AMQP protocol implementation for azure-servicebus, uAMQP wheels can be found for most major operating systems.

If you're running on a platform for which uAMQP wheels are not provided, please follow If you intend to use uAMQP and you're running on a platform for which uAMQP wheels are not provided, please follow the uAMQP Installation guidance to install from source.
