# Rocksdb Change Log
## Unreleased
### New Features
### Bug Fixes
### Behavior Changes

@ -24,6 +30,7 @@
* Users who configured a dedicated thread pool for bottommost compactions by explicitly adding threads to the `Env::Priority::BOTTOM` pool will no longer see RocksDB schedule automatic compactions exceeding the DB's compaction concurrency limit. For details on per-DB compaction concurrency limit, see API docs of `max_background_compactions` and `max_background_jobs`.
* Fixed a bug of background flush thread picking more memtables to flush and prematurely advancing column family's log_number.
* Fixed an assertion failure in ManifestTailer.
* Fixed a bug that could, with WAL enabled, cause backups, checkpoints, and `GetSortedWalFiles()` to fail randomly with an error like `IO error: 001234.log: No such file or directory`
### Behavior Changes
* `NUM_FILES_IN_SINGLE_COMPACTION` was only counting the first input level files, now it's including all input files.
