It’s time to upgrade to Cassandra 4.1

The latest release of Apache Cassandra, version 4.1, focuses on improving security and operations for users. New features include system tables to enhance security and monitoring, as well as tools like CEP-10 for simulating cluster operations. Additionally, the Cassandra community is working on landmark features such as full ACID transactions and relational-style secondary indexes for future releases. The ecosystem surrounding Cassandra continues to grow with new pluggable implementations and projects like Stargate and K8ssandra. Upgrades from 4.0 to 4.1 are primarily focused on security and operations, but developers can also look forward to improvements in configuration management.
