RocksDB 5.8 发布,可持久化 key-value 存储系统

  • Users of Statistics::getHistogramString() will see fewer histogram buckets and different bucket endpoints.
  • Slice::compare and BytewiseComparator Compare no longer accept Slices containing nullptr.
  • Transaction::Get and Transaction::GetForUpdate variants with PinnableSlice added.

New Features

  • Add Iterator::Refresh(), which allows users to update the iterator state so that they can avoid some initialization costs of recreating iterators.
  • Replace dynamic_cast<> (except unit test) so people can choose to build with RTTI off. With make, release mode is by default built with -fno-rtti and debug mode is built without it. Users can override it by setting USE_RTTI=0 or 1.
