Distributed disk storage database based on Raft and Redis protocol.

IceFireDB

Distributed disk storage system based on Raft and RESP protocol.

1. High performance
2. Distributed consistency
3. Reliable LSM disk storage
4. Cold and hot mixed data storage structure（Upgrading soon）
5. Multiple groups of raft clusters, horizontal expansion and contraction of data groups
6. More advanced cache implementation, faster LSM persistent storage
