- update to 8.3.2
* Bug Fixes:
Reduced cases of illegally using Env::Default() during static destruction by never destroying the internal PosixEnv itself
- update to 8.3.1
* Performance Improvements:
Fixed higher read QPS during DB::Open() reading files created prior to #11406,
- update to 8.3.0
* New Features:
Introduced a new option block_protection_bytes_per_key, which can be used to enable per key-value integrity protection for in-memory blocks in block cache
Improve the operational safety of publishing a DB or SST files to many hosts by using different block cache hash seeds on different hosts.
Introduced a new option CompactionOptionsFIFO::file_temperature_age_thresholds that allows FIFO compaction to compact files to different temperatures based on key age
Added a new ticker stat to count how many times RocksDB detected a corruption while verifying a block checksum: BLOCK_CHECKSUM_MISMATCH_COUNT.
New statistics rocksdb.file.read.db.open.micros that measures read time of block-based SST tables or blob files during db open.
New statistics tickers for various iterator seek behaviors and relevant filtering, as *_LEVEL_SEEK_*. (#11460)
* Public API Changes:
EXPERIMENTAL: Add new API DB::ClipColumnFamily to clip the key in CF to a certain range. It will physically deletes all keys outside the range including tombstones.
Add MakeSharedCache() construction functions to various cache Options objects, and deprecated the NewWhateverCache() functions with long parameter lists.
Changed the meaning of various Bloom filter stats (prefix vs. whole key), with iterator-related filtering only being tracked in the new *_LEVEL_SEEK_*. stats. (#11460)
* Behavior changes:
For x86, CPU features are no longer detected at runtime nor in build scripts, but in source code using common preprocessor defines.
This will likely unlock some small performance improvements on some newer hardware, but could hurt performance of the kCRC32c checksum,
which is no longer the default, on some "portable" builds. See PR #11419 for details.
* Bug Fixes:
Delete an empty WAL file on DB open if the log number is less than the min log number to keep
Delete temp OPTIONS file on DB open if there is a failure to write it out or rename it
* Performance Improvements:
Improved the I/O efficiency of prefetching SST metadata by recording more information in the DB manifest.
