The ScyllaDB team is pleased to announce the release of ScyllaDB 2.1.6, a bugfix release of the ScyllaDB 2.1 stable branch. Release 2.1.6, like all past and future 2.x.y releases, is backward compatible and supports rolling upgrades.
ScyllaDB 2.1.6 fixes one critical issue with the caching of data for DateTiered or TimeWindow compaction strategies. If you are using either of these strategies, we recommend upgrading ASAP. The critical issue is: In some cases when using DateTiered or TimeWindow compaction strategies, a partition can start to appear empty until ScyllaDB is restarted. The problem is in the cache logic, while the data itself is safely persistent on disk. #3552
Additional Issue Resolved in This Release
- Reads which are using clustering key restrictions (including paging reads) may be missing some of the deletions and static row writes for DateTiered and TimeWindow compaction strategies. Similar to #3552, data on the disk is not affected. #3553
