RocksDB 4.1 发布下载,更新内容如下:

新特性

  • Added single delete operation as a more efficient way to delete keys that have not been overwritten.
  • Added experimental AddFile() to DB interface that allow users to add files created by SstFileWriter into an empty Database, see include/rocksdb/sst_file_writer.h and DB::AddFile() for more info.
  • Added support for opening SST files with .ldb suffix which enables opening LevelDB databases.
  • CompactionFilter now supports filtering of merge operands and merge results.

公共 API 更新

  • Added SingleDelete() to the DB interface.
  • Added AddFile() to DB interface.
  • Added SstFileWriter class.
  • CompactionFilter has a new method FilterMergeOperand() that RocksDB applies to every merge operand during compaction to decide whether to filter the operand.
  • We removed CompactionFilterV2 interfaces from include/rocksdb/compaction_filter.h. The functionality was deprecated already in version 3.13.
