When it is on, DB::Open() will run faster as it skips the random reads required for loading necessary stats from SST files to optimize compaction. * RollbackToSavePoint() in WriteBatch/WriteBatchWithIndex * Add NewCompactOnDeletionCollectorFactory() in utilities/table_properties_collectors, which allows rocksdb to mark a SST file as need-compaction when it observes at least D deletion entries in any N consecutive entries in that SST file. Note that this feature depends on an experimental NeedCompact() API --- the result of this API will not persist after DB restart. * Add DBOptions::delete_scheduler. Use NewDeleteScheduler() in include/rocksdb/delete_scheduler.h to create a DeleteScheduler that can be shared among multiple RocksDB instances to control the file deletion rate of SST files that exist in the first db_path. -* Add statistics::getHistogramString() to print detailed distribution of a histogram metric. ### Public API Changes * Deprecated WriteOptions::timeout_hint_us. We no longer support write timeout. If you really need this option, talk to us and we might consider returning it. @@ -15,6 +12,8 @@ * Removed BackupEngine::NewBackupEngine() and NewReadOnlyBackupEngine() that were deprecated in RocksDB 3.8. Please use BackupEngine::Open() instead. * Deprecated Compaction Filter V2. We are not aware of any existing use-cases. If you use this filter, your compile will break with RocksDB 3.13. Please let us know if you use it and we'll put it back in RocksDB 3.14. * Env::FileExists now returns a Status instead of a boolean +* Add statistics::getHistogramString() to print detailed distribution of a histogram metric. +* Add DBOptions::skip_stats_update_on_db_open.
