We are frequently asked: Should we use the DataStax Driver for DSE (often referred to as the DSE Driver) or the DataStax Driver for Apache Cassandra (often referred to as the OSS Driver)? What is the Difference? Which driver performs better? Is DataStax going to continue to support the OSS Drivers and DSE Drivers?
As of January 2020, DataStax merged all of the DSE drivers functionality into the existing OSS drivers and all new features will be developed in the OSS drivers going forward, both for Apache Cassandra and DataStax Enterprise. Bug fixes for the DSE drivers will continue to be addressed until January 1st, 2022. This new version of the DataStax driver is open source and Apache License v2.0.
If you are currently using the latest version of a DSE driver, upgrading to the newest version of the OSS drivers requires a driver version change and altering your imports to match the new locations of the DSE driver functionality in the OSS driver. There are no changes to the API in this upgrade.
