RocksDB: A Persistent Key-Value Store for Flash and RAM Storage (github.com)

Differences from leveldb: https://github.com/facebook/rocksdb/wiki/Features-Not-in-Lev...

Has been using it in production for quite a long time now, wrote my own key-value store server running on top of RocksDB. I hope somebody writes a good and stable key value store server, I tried using ardb (https://github.com/yinqiwen/ardb) but was not happy with it's memory consumption.

https://github.com/pingcap/tikv stores consensus state in RocksDB. > With the implementation of the Raft consensus algorithm in Rust and consensus state stored in RocksDB, it guarantees data consistency.
