The Progress® DataDirect® for JDBC™ for Apache Cassandra™ driver supports SQL read-write access to DataStax Enterprise 4.6 or higher and Apache Cassandra 2.0 or higher. To support SQL access to Cassandra, the driver creates a relational map of native Cassandra data and translates SQL statements to CQL. Cassandra complex data types Map, List, Set, Tuple, and user-defined types are supported alongside primitive CQL types. The driver optimizes performance when executing joins by leveraging data relationships among Cassandra objects to minimize the amount of data that needs to be fetched over the network. Relationships among objects can be reported with the metadata methods getTables(), getColumns(), getTypeInfo(), getPrimaryKeys(), getExportedKeys(), and getBestRowIdentifier().

The documentation for the driver also includes the Progress DataDirect for JDBC Drivers Reference. The reference provides general reference information for all DataDirect drivers for JDBC, including content on troubleshooting, supported SQL escapes, and DataDirect tools.
