新闻 RocksDB 5.8 发布，可持久化 key-value 存储系统 下载

RocksDB 8 已发布，RocksDB 是一个来自 Facebook 的可嵌入式的支持持久化的 key-value 存储系统，也可作为 C/S 模式下的存储数据库，但主要目的还是嵌入式。RocksDB 基于 LevelDB 构建。

更新内容如下：

Public API Change

• 
  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.
