Here are some of the key features introduced in Cassandra 4:

  • Enhanced Metrics via virtual tables
  • Workload replay with full query logging*
  • Audit logging for enhanced compliance*
  • Zero Copy Streaming

*Not available yet, but will soon be included in Aiven for Apache Cassandra.

Full details on all of the new features are listed on the Cassandra 4.0 web page:
