Bug Fixes

• Fix a bug where tail size of remote compaction output is not persisted in primary db's manifest

10.1.0 (03/24/2025)

New Features

• Added a new DBOptions.calculate_sst_write_lifetime_hint_set setting that allows to customize which compaction styles SST write lifetime hint calculation is allowed on. Today RocksDB supports only two modes kCompactionStyleLevel and kCompactionStyleUniversal.
• Add a new field num_l0_files in CompactionJobInfo about the number of L0 files in the CF right before and after the compaction
• Added per-key-placement feature in Remote Compaction
• Implemented API DB::GetPropertiesOfTablesByLevel that retrieves table properties for files in each LSM tree level

Public API Changes

• GetAllKeyVersions() now interprets empty slices literally, as valid keys, and uses new OptSlice type default value for extreme upper and lower range limits.
• DeleteFilesInRanges() now takes RangeOpt which is based on OptSlice. The overload taking RangePtr is deprecated.
• Add an unordered map of name/value pairs, ReadOptions::property_bag, to pass opaque options through to an external table when creating an Iterator.
• Introduced CompactionServiceJobStatus::kAborted to allow handling aborted scenario in Schedule(), Wait() or OnInstallation() APIs in Remote Compactions.
• format_version < 2 in BlockBasedTableOptions is no longer supported for writing new files. Support for reading such files is deprecated and might be removed in the future. CompressedSecondaryCacheOptions::compress_format_version == 1 is also deprecated.

Behavior Changes

• ldb now returns an error if the specified --compression_type is not supported in the build.
• MultiGet with snapshot and ReadOptions::read_tier = kPersistedTier will now read a consistent view across CFs (instead of potentially reading some CF before and some CF after a flush).
• CreateColumnFamily() is no longer allowed on a read-only DB (OpenForReadOnly())

Bug Fixes

• Fixed stats for Tiered Storage with preclude_last_level feature
