Bump rocksdb to v9.8.4, a first release in 9.8 release. Full changelog - https://github.com/facebook/rocksdb/releases/tag/v9.8.4 **Important to us**: addition fixes about leak file descriptions for blobs **Key features** - When Remote Compaction is enabled, do not purge OPTIONS file immediately by DeleteObsoleteOptionsFiles() after SetOptions(). Rely on PurgeObsoleteFiles() to clean up obsolete OPTIONS file after each compaction - Added a new API Transaction::GetAttributeGroupIterator that can be used to create a multi-column-family attribute group iterator over the specified column families - All non-block_cache options in BlockBasedTableOptions are now mutable with DB::SetOptions() - When using iterators with BlobDB, it is now possible to load large values on an on-demand basis, i.e. only if they are actually needed by the application. This can save I/O in use cases where the values associated with certain keys are not needed - The option allow_unprepared_value is now also supported for multi-column-family iterators - OPTIONS file to be loaded by remote worker is now preserved so that it does not get purged by the primary host - Trim readahead_size during scans so data blocks containing keys that are not in the same prefix as the seek key in Seek() are not prefetched when ReadOptions::auto_readahead_size=true (default value) and ReadOptions::prefix_same_as_start = true - Assigning levels for external files are done in the same way for universal compaction and leveled compaction **Bug fixed** - Fix missing cases of corruption retry during DB open and read API processing - Fix a bug for replaying WALs for WriteCommitted transaction DB when its user-defined timestamps setting is toggled on/off between DB sessions - Fix a leak of obsolete blob files left open until DB::Close(). This bug was introduced in version 9.4.0. - Fix a longstanding race condition in SetOptions for block_based_table_factory options - Fix under counting of allocated memory in the compressed secondary cache due to looking at the compressed block size rather than the actual memory allocated - Skip insertion of compressed blocks in the secondary cache if the lowest_used_cache_tier DB option is kVolatileTier - Fix an issue in level compaction where a small CF with small compaction debt can cause the DB to allow parallel compactions. - Several DB option settings could be lost through GetOptionsFromString(), possibly elsewhere as well. Affected options, now fixed:background_close_inactive_wals, write_dbid_to_manifest, write_ identity_file, prefix_seek_opt_in_only -- This is an automated message from the Apache Git Service.
