Progress DataDirect for JDBC for Apache Cassandra

An asterisk (*) indicates support that was added in a hotfix or software patch subsequent to a release.

Version 6.0.0

Certifications
  • Certified with Apache Cassandra 3.x*
  • Certified with Apache Cassandra 2.x
Enhancements
  • The driver has been enhanced to support Cassandra's tunable consistency functionality with the ReadConsistency and WriteConsistency connection
    properties.*
  • The driver has been enhanced to improve the handling of large result sets and
    reduce the likelihood of out-of-memory errors through the introduction of the
    FetchSize, NativeFetchSize, and ResultMemorySize connection properties.*
GA Release Features
  • Supports SQL read-write access to Apache Cassandra 2.0 and higher
  • Generates a normalized view of Cassandra data. Tuple and user-defined types are flattened into a relational parent table, while collection types are mapped as relational child tables.
  • Supports Native and Refresh escape sequences to embed CQL commands in SQL-92 statements.
  • Includes the TransactionMode connection property which allows you to configure the driver to report that it supports transactions, even though Cassandra does not support transactions. This provides a workaround for applications that do not operate with a driver that reports transactions are not supported.
  • Support for Binary Large Objects (BLOBs)
  • Support for connection pooling
  • Support for statement pooling
  • Includes the LoginTimeout connection property which allows you to specify how long the driver waits for a connection to be established before timing out the connection request.
