Issue fixed in this release:
- Performance: Compaction manager “periodic reevaluation” is one-off. This means that compaction was not kicking in later for a table, with low to none write activity, that had expired data 1 hour from now. #13430
- Performance: Compaction manager can cause reactor stalls during periodic submission #12390
- Performance: ScyllaDB uses an interval map data structure from the Boost library to quickly locate sstables needed to service a read. Due to the way we interface with the library, updating the interval map was unnecessarily slow. This is now fixed. #11669
- Performance: SSTable set is left uncompacted post off-strategy compaction completion, which may lead to suboptimal read and space amplification until the next compaction #13429
- Stability: ‘sleep_aborted’ error during Scylla shutdown #13374
- Stability: Use-after-move when reading from SSTable in reverse #13394
- Stability: Use-after-move when tracking view builder progress #13395
- Stability: Use-after-move in virtual table for secondary indexes #13396
- Stability: Use-after-move when making streaming reader #13397
- Stability: Use-after-move when initializing row cache with dummy entry #13400
- UX: non informative iotune warnings in scylla_kernel_check #13373
