New Features

  • Add include/utilities/write_batch_with_index.h, providing a utility class to query data out of WriteBatch when building it.
  • new ReadOptions.total_order_seek to force total order seek when block-based table is built with hash index.

Public API changes

  • The Prefix Extractor used with V2 compaction filters is now passed user key to SliceTransform::Transform instead of unparsed RocksDB key.
  • Move BlockBasedTable related options to BlockBasedTableOptions from Options. Change corresponding JNI interface. Options affected include: no_block_cache, block_cache, block_cache_compressed, block_size, block_size_deviation, block_restart_interval, filter_policy, whole_key_filtering. filter_policy is changed to shared_ptr from a raw pointer.
  • Remove deprecated options: disable_seek_compaction and db_stats_log_interval
  • OptimizeForPointLookup() takes one parameter for block cache size. It now builds hash index, bloom filter, and block cache.
