- update to 8.8.1
* Bug fixes:
- Make the cache memory reservation accounting in Tiered cache
(primary and compressed secondary cache) more accurate to avoid over/under charging the secondary cache.
- Allow increasing the compressed_secondary_ratio in the Tiered cache after setting it to 0 to disable.
- update to 8.8.0
* New features:
- Introduce AttributeGroup by adding the first AttributeGroup support API, MultiGetEntity().
- Added new tickers rocksdb.fifo.{max.size|ttl}.compactions to count FIFO compactions
that drop files for different reasons
- Add an experimental offpeak duration awareness by setting DBOptions::daily_offpeak_time_utc in "HH:mm-HH:mm" format.
- Users can now change the max bytes granted in a single refill period (i.e, burst) during runtime
by SetSingleBurstBytes() for RocksDB rate limiter
* Public API Changes:
- The default value of DBOptions::fail_if_options_file_error changed from false to true.
- Add new Cache APIs GetSecondaryCacheCapacity() and GetSecondaryCachePinnedUsage()
to return the configured capacity, and cache reservation charged to the secondary cache.
* Behavior Changes:
- For non direct IO, eliminate the file system prefetching attempt for compaction read
when Options::compaction_readahead_size is 0
- During a write stop, writes now block on in-progress recovery attempts
- Deleting stale files upon recovery are delegated to SstFileManger if available so they can be rate limited.
* Bug Fixes
- 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.
- Fixed a bug where compaction read under non direct IO still falls back to RocksDB internal prefetching
after file system's prefetching returns non-OK status other than Status::NotSupported()
- Add bounds check in WBWIIteratorImpl and make BaseDeltaIterator, WriteUnpreparedTxn and WritePreparedTxn
respect the upper bound and lower bound in ReadOption.
- Fixed the handling of wide-column base values in the max_successive_merges logic.
