ScyllaDB Open Source Release 2.1.4

ScyllaDB Open Source 2.1.4 has been released as a bugfix update to the 2.1 stable branch, addressing a critical issue related to data loss when using the Leveled Compaction Strategy (LCS). This problem, which emerged during full table scans and affected processes like decommissioning, node addition, and repairs, was attributed to a low-level optimization in the 2.1 release that was missed in initial testing. Users employing LCS are urged to upgrade to 2.1.4 immediately, and those with relevant backups should contact support for restoration guidance. The release also fixes several other bugs, including issues with systemd in ScyllaDB AMI, RAID 0 data directory access, commit log error handling, and TLS connection errors. The developers are committed to improving the cluster test suite to prevent future oversights and will provide a detailed root cause analysis and subsequent enhancements.
