With the goal of ensuring reliability and stability in Apache Cassandra 4.0, the project’s committers have voted to freeze new features on September 1 to concentrate on testing and validation before cutting a stable beta. Towards that goal, the community is investing in methodologies that can be performed at scale to exercise edge cases in the largest Cassandra clusters. The result, we hope, is to make Apache Cassandra 4.0 the best-tested and most reliable major release right out of the gate.

Streaming in Apache Cassandra powers host replacement, range movements, and cluster expansions. Streaming plays a crucial role in the cluster and as such its performance is key to not only the speed of the operations its used in but the cluster’s health generally. In Apache Cassandra 4.0, we have introduced an improved streaming implementation that reduces GC pressure and increases throughput several folds and are now limited, in some cases, only by the disk / network IO (See: CASSANDRA-14556).
