Overview
The Akka Persistence Cassandra plugin allows for using Apache Cassandra as a backend for Akka Persistence and Akka Persistence Query. It uses Alpakka Cassandra for Cassandra access which is based on the Datastax Java Driver.

Note that it is important that all akka-*
dependencies are in the same version, so it is recommended to depend on them explicitly to avoid problems with transient dependencies causing an unlucky mix of versions.
The table below shows Akka Persistence Cassandra’s direct dependencies and the second tab shows all libraries it depends on transitively.

History
This Apache Cassandra plugin to Akka Persistence was initiated originally by Martin Krasser, @krasserm in 2014.
It moved to the Akka organisation in 2016 and the first release after that move was 0.7 in January 2016.
