# Apache Cassandra 2.x CQL binding
|
|
|
|
Binding for [Apache Cassandra](http://cassandra.apache.org), using the CQL API
|
|
via the [DataStax
|
|
driver](http://docs.datastax.com/en/developer/java-driver/2.1/java-driver/whatsNew2.html).
|
|
|
|
To run against the (deprecated) Cassandra Thrift API, use the `cassandra-10` binding.
|
|
|
|
## Creating a table for use with YCSB
|
|
|
|
For keyspace `ycsb`, table `usertable`:
|
|
|
|
cqlsh> create keyspace ycsb
|
|
WITH REPLICATION = {'class' : 'SimpleStrategy', 'replication_factor': 3 };
|
|
cqlsh> USE ycsb;
|
|
cqlsh> create table usertable (
|
|
y_id varchar primary key,
|
|
field0 varchar,
|
|
field1 varchar,
|
|
field2 varchar,
|
|
field3 varchar,
|
|
field4 varchar,
|
|
field5 varchar,
|
|
field6 varchar,
|
|
field7 varchar,
|
|
field8 varchar,
|
|
field9 varchar);
|
|
|
|
**Note that `replication_factor` and consistency levels (below) will affect performance.**
|
|
|
|
## Cassandra Configuration Parameters
|
|
|
|
- `hosts` (**required**)
|
|
- Cassandra nodes to connect to.
|
|
- No default.
|
|
|
|
* `port`
|
|
* CQL port for communicating with Cassandra cluster.
|
|
* Default is `9042`.
|
|
|
|
- `cassandra.keyspace`
|
|
Keyspace name - must match the keyspace for the table created (see above).
|
|
See http://docs.datastax.com/en/cql/3.1/cql/cql_reference/create_keyspace_r.html for details.
|
|
|
|
- Default value is `ycsb`
|
|
|
|
- `cassandra.username`
|
|
- `cassandra.password`
|
|
- Optional user name and password for authentication. See http://docs.datastax.com/en/cassandra/2.0/cassandra/security/security_config_native_authenticate_t.html for details.
|
|
|
|
* `cassandra.readconsistencylevel`
|
|
* `cassandra.writeconsistencylevel`
|
|
|
|
* Default value is `QUORUM`
|
|
- Consistency level for reads and writes, respectively. See the [DataStax documentation](http://docs.datastax.com/en/cassandra/2.0/cassandra/dml/dml_config_consistency_c.html) for details.
|
|
|
|
* `cassandra.maxconnections`
|
|
* `cassandra.coreconnections`
|
|
* Defaults for max and core connections can be found here: https://datastax.github.io/java-driver/2.1.8/features/pooling/#pool-size. Cassandra 2.0.X falls under protocol V2, Cassandra 2.1+ falls under protocol V3.
|
|
* `cassandra.connecttimeoutmillis`
|
|
* `cassandra.useSSL`
|
|
* Default value is false.
|
|
- To connect with SSL set this value to true.
|
|
* `cassandra.readtimeoutmillis`
|
|
* Defaults for connect and read timeouts can be found here: https://docs.datastax.com/en/drivers/java/2.0/com/datastax/driver/core/SocketOptions.html.
|
|
* `cassandra.tracing`
|
