- update to 8.11.3:
* Bug Fixes
+ Fix a bug where older data of an ingested key can be returned for read when universal compaction is used
+ Apply appropriate rate limiting and priorities in more places.
- update to 8.11.0:
* New Features
+ Add new statistics: rocksdb.sst.write.micros measures time of each write to SST file
* Public API Changes
+ Added another enumerator kVerify to enum class FileOperationType in listener.h.
Update your switch statements as needed.
+ Add CompressionOptions to the CompressedSecondaryCacheOptions structure to allow users to specify
library specific options when creating the compressed secondary cache.
+ Deprecated several options: level_compaction_dynamic_file_size, ignore_max_compaction_bytes_for_input,
+ check_flush_compaction_key_order, flush_verify_memtable_count, compaction_verify_record_count,
fail_if_options_file_error, and enforce_single_del_contracts
+ Exposed options ttl via c api.
* Behavior Changes
+ rocksdb.blobdb.blob.file.write.micros expands to also measure time writing the header and footer.
Therefore the COUNT may be higher and values may be smaller than before. For stacked BlobDB,
it no longer measures the time of explictly flushing blob file.
+ Files will be compacted to the next level if the data age exceeds periodic_compaction_seconds
except for the last level.
+ Reduced the compaction debt ratio trigger for scheduling parallel compactions
+ For leveled compaction with default compaction pri (kMinOverlappingRatio),
files marked for compaction will be prioritized over files not marked when picking a file
from a level for compaction.
* Bug Fixes
+ Fix bug in auto_readahead_size that combined with IndexType::kBinarySearchWithFirstKey + fails
or iterator lands at a wrong key
+ Fixed some cases in which DB file corruption was detected but ignored on creating a backup with BackupEngine.
