on GitHub

8.5.3 (09/01/2023)

Bug Fixes

• Fixed a race condition in GenericRateLimiter that could cause it to stop granting requests

8.5.2 (08/31/2023)

Bug fixes

• Fix a bug where iterator may return incorrect result for DeleteRange() users if there was an error reading from a file.

8.5.1 (08/31/2023)

Bug fixes

• Fix a bug where if there is an error reading from offset 0 of a file from L1+ and that the file is not the first file in the sorted run, data can be lost in compaction and read/scan can return incorrect results.

8.5.0 (07/21/2023)

Public API Changes

• Removed recently added APIs GeneralCache and MakeSharedGeneralCache() as our plan changed to stop exposing a general-purpose cache interface. The old forms of these APIs, Cache and NewLRUCache(), are still available, although general-purpose caching support will be dropped eventually.

Behavior Changes

• Option periodic_compaction_seconds no longer supports FIFO compaction: setting it has no effect on FIFO compactions. FIFO compaction users should only set option ttl instead.
• Move prefetching responsibility to page cache for compaction read for non directIO use case

Performance Improvements

• In case of direct_io, if buffer passed by callee is already aligned, RandomAccessFileRead::Read will avoid realloacting a new buffer, reducing memcpy and use already passed aligned buffer.
• Small efficiency improvement to HyperClockCache by reducing chance of compiler-generated heap allocations

Bug Fixes

• Fix use_after_free bug in async_io MultiReads when underlying FS enabled kFSBuffer. kFSBuffer is when underlying FS pass their own buffer instead of using RocksDB scratch in FSReadRequest. Right now it's an experimental feature.
• Fix a bug in FileTTLBooster that can cause users with a large number of levels (more than 65) to see errors like "runtime error: shift exponent .. is too large.." (#11673).
