| # Cassandra (0.7, 0.8, 1.x) drivers for YCSB | ||
|
|
||
| **For Cassandra 2 CQL support, use the `cassandra2-cql` binding. The Thrift drivers below are deprecated, and the CQL driver here does not support Cassandra 2.1+.** | ||
|
|
||
| There are three drivers in the Cassandra binding: | ||
|
|
||
| * `cassandra-7`: Cassandra 0.7 Thrift binding. | ||
| * `cassandra-8`: Cassandra 0.8 Thrift binding. | ||
| * `cassandra-10`: Cassandra 1.0+ Thrift binding. | ||
| * `cassandra-cql`: Cassandra CQL binding, for Cassandra 1.x to 2.0. See `cassandra2/README.md` for details on parameters. | ||
|
|
||
| # `cassandra-10` | ||
|
|
||
| ## Creating a table | ||
|
|
||
| Using `cassandra-cli`: | ||
|
|
||
| create keyspace usertable with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy' and strategy_options = {replication_factor:1}; | ||
|
|
||
| create column family data with column_type = 'Standard' and comparator = 'UTF8Type'; | ||
|
|
||
| **Note that `replication_factor` and consistency levels (below) will affect performance.** | ||
|
|
||
| ## Configuration Parameters | ||
|
|
||
| - `hosts` (**required**) | ||
| - Cassandra nodes to connect to. | ||
| - No default. | ||
|
|
||
| * `port` | ||
| - Thrift port for communicating with Cassandra cluster. | ||
| * Default is `9160`. | ||
|
|
||
| - `cassandra.columnfamily` | ||
| - Column family name - must match the column family for the table created (see above). | ||
| - Default value is `data` | ||
|
|
||
| - `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.scanconsistencylevel` | ||
| * `cassandra.writeconsistencylevel` | ||
|
|
||
| - Default value is `ONE` | ||
| - 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. | ||
| - *Note that the default setting does not provide durability in the face of node failure. Changing this setting will affect observed performance.* See also `replication_factor`, above. |

| # 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 `ONE` | ||
| - 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. | ||
| * *Note that the default setting does not provide durability in the face of node failure. Changing this setting will affect observed performance.* See also `replication_factor`, above. |
