  • Learn about the new pluggable interfaces and other 4.1 features you can use to tailor your Cassandra deployment to your environment:
  • Pluggable storage
  • Pluggable network encryption
  • Pluggable authentication
  • External schema storage
  • Guardrails
  • Celebrate our open source community with highlights from the 2022 Apache Cassandra World Party.
