ScyllaDB 2.1.1, released by the ScyllaDB team, is a bugfix update for the ScyllaDB 2.1 stable branch, maintaining backward compatibility and supporting rolling upgrades. ScyllaDB, an open-source NoSQL database compatible with Apache Cassandra, is known for its superior performance and low latency. The new release addresses critical bugs, including a failure when querying partitions without clustering ranges and a regression in version 2.1.0 that caused crashes during initialization. It also resolves a gossip bug that led to segmentation faults when nodes were down. Users of ScyllaDB 1.7 or earlier versions are encouraged to upgrade to benefit from ongoing bug fixes and new features being developed for future iterations, such as ScyllaDB 2.2.
