9.5.2 (08/13/2024)

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.

*Make DestroyDB supports slow deletion when it's configured in SstFileManager. The slow deletion is subject to the configured rate_bytes_per_sec, but not subject to the max_trash_db_ratio.

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

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 where OnErrorRecoveryBegin() is not called before auto recovery starts.
Fixed a bug where event listener reads ErrorHandler's bg_error_ member without holding db mutex(#12803).
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. Both attempt to write a new manifest file, which causes an assertion failure.

Fix an issue where compactions were opening table files and reading table properties while holding db mutex_.
Reduce unnecessary filesystem queries and DB mutex acquires in creating backups and checkpoints.
