Cassandra 6.0 introduces ACID transactions and coordinated metadata, easing app complexity
Apache Cassandra 6.0 adds Accord, a leaderless consensus protocol that provides ACID transaction semantics with serializable isolation across partitions, moving coordination logic from application code into the database. It also launches Transactional Cluster Metadata (TCM), a service that ensures consistent cluster metadata during schema and topology changes, improving reliability and simplifying operations.
