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 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.
