kvrocks is an open-source key-value database. which is based on rocksdb and compatible with Redis protocol. Intention to decrease the cost of memory and increase the capability while compared to Redis. The design of replication and storage was inspired by rocksplicator and blackwidow.
kvrocks has the following key features:
- Redis protocol, user can use redis client to visit the kvrocks
- Namespace, similar to redis db but use token per namespace
- Replication, async replication using binlog like MySQL
- High Available, supports redis sentinel to failover when master or slave was failed
- gcc-g++ (required by c++11, version >= 4.8)
- autoconf (required by jemalloc)

namespace was used to isolate data between users. unlike all the redis databases can be visited by requirepass, we use one token per namespace. requirepass was regraded as admin token, only admin token allows to access the namespace command, as well as some commands like config, slaveof, bgave, etc…
