DataStax drivers for open-source Cassandra (OSS) and DSE

Note: Starting January 2020, you can use the same DataStax driver for Apache Cassandra® (OSS), DataStax Enterprise, and DataStax Distribution of Apache Cassandra. DataStax has unified the DSE and OSS drivers to avoid user confusion and enhance the OSS drivers with some of the features in the DSE drivers. For more information, see the Better Drivers for Cassandra blog.
  • DSE drivers are supported until January 1st, 2022. However, all new features and functionality will take place only in the unified DataStax drivers.
