Bump rocksdb to 8.7.3 (#1902)
Update rocksdb to v8.7.3. Full release notes here -
https://github.com/facebook/rocksdb/releases/tag/v8.7.3
Critical changes include:
- Add new Cache APIs GetSecondaryCacheCapacity() and
GetSecondaryCachePinnedUsage()
- A few bugs in cache subsystem are fixed
- Fix a bug in auto_readahead_size where first_internal_key of index blocks
wasn't copied properly resulting in corruption error when first_internal_key
was used for comparison
- Fix a bug where row cache can falsely return kNotFound even though row
cache entry is hit.
- Fixed a race condition in GenericRateLimiter that could cause it to stop
granting requests
- A lot of bugs are fixed (in cache, in async_io, in compaction etc.)
- (Perf) Added additional improvements in tuning readahead_size during
Scans when auto_readahead_size is enabled
- (Perf) During async_io, the Seek happens in 2 phases. Phase 1 starts an
asynchronous read on a block cache miss, and phase 2 waits for it to complete
and finishes the seek. In both phases, it tries to lookup the block cache for
the data block first before looking in the prefetch buffer. It's optimized by
doing the block cache lookup only in the first phase that would save some CPU.
- Universal size amp compaction will conditionally exclude some of the
newest L0 files when selecting input with a small negative impact to size amp.
This is to prevent a large number of L0 files from being locked by a size amp
compaction, potentially leading to write stop with a few more flushes.
- Options::compaction_readahead_size 's default value is changed from 0 to
2MB.
- Added a new wide-column aware full merge API called FullMergeV3 to
MergeOperator. FullMergeV3 supports wide columns both as base value and merge
result, which enables the application to perform more general transformations
during merges. For backward compatibility, the default implementation
implements the earlier logic of applying the merge operation to the default
column of any wide-column entities.
- Add a new statistic COMPACTION_CPU_TOTAL_TIME that records cumulative
compaction cpu time.
- Added an experimental new "automatic" variant of HyperClockCache that
does not require a prior estimate of the average size of cache entries
