URL: https://github.com/apache/kvrocks/pull/2502
Bump rocksdb to v9.5.2, a first release at 9.5, full changelog -
https://github.com/facebook/rocksdb/releases/tag/v9.5.2
**Key features**
- Introduced new C API function rocksdb_writebatch_iterate_cf for column
family-aware iteration over the contents of a WriteBatch
- Add support to ingest SST files generated by a DB instead of
SstFileWriter. This can be enabled with experimental option
IngestExternalFileOptions::allow_db_generated_files
- When calculating total log size for the log_size_for_flush argument in
CreateCheckpoint API, the size of the archived log will not be included to
avoid unnecessary flush
- Reduce unnecessary filesystem queries and DB mutex acquires in creating
backups and checkpoints
- Add ticker stats to count file read retries due to checksum mismatch
**Bug fix**
- Fix an issue where compactions were opening table files and reading table
properties while holding db mutex_
- Fix a major bug in which an iterator using prefix filtering and
SeekForPrev might miss data when the DB is using whole_key_filtering=false and
partition_filters=true
- Fixed a bug in handling MANIFEST write error that caused the latest valid
MANIFEST file to get deleted, resulting in the DB being unopenable
- Fixed a race between error recovery due to manifest sync or write failure
and external SST file ingestion
- Fix a race condition in pessimistic transactions that could allow multiple
transactions with the same name to be registered simultaneously, resulting in a
crash or other unpredictable behavior
