### Performance Improvements ### Performance Improvements
* Fixed an iterator performance regression for delete range users when scanning through a consecutive sequence of range tombstones (#10877). * Fixed an iterator performance regression for delete range users when scanning through a consecutive sequence of range tombstones (#10877).
### Bug Fixes
* Fix FIFO compaction causing corruption of overlapping seqnos in L0 files due to ingesting files of overlapping seqnos with memtable's under `CompactionOptionsFIFO::allow_compaction=true` or `CompactionOptionsFIFO::age_for_warm>0` or `CompactRange()/CompactFiles()` is used. Before the fix, `force_consistency_checks=true` may catch the corruption before it's exposed to readers, in which case writes returning `Status::Corruption` would be expected.

* Try to align the compaction output file boundaries to the next level ones, which can reduce more than 10% compaction load for the default level compaction. The feature is enabled by default, to disable, set `AdvancedColumnFamilyOptions.level_compaction_dynamic_file_size` to false. As a side effect, it can create SSTs larger than the target_file_size (capped at 2x target_file_size) or smaller files. * Try to align the compaction output file boundaries to the next level ones, which can reduce more than 10% compaction load for the default level compaction.
