Wrap RocksDB inside a server talks like the REDIS.

For now, I am using tecbot/gorocksdb Go wrapper for RocksDB which needs his fork of RocksDB.

Dependencies:

• RocksDB: github.com/tecbot/rocksdb
• RocksDB Go Wrapper: github.com/tecbot/gorocksdb
• go get code.google.com/p/gcfg

Support commands:

• Keys: del, type, exists, keys
• Strings: getset, get, set, mget, mset, append, incr, incrby, decr, decrby
• Lists: lpush, rpush, lpop, rpop, lrange, lindex, llen, ltrim
• Hashes: hset, hget, hgetall, hexists, hdel, hkeys, hvals, hlen, hmget, hmset
• Sets : sadd, srem, smembers, scard, sismember

Config:

Please refer to rockdis.conf for example.

$ go run *.go -conf=rockdis.conf

Then, you can just use the redis-cli command line to try the server.

Some Tests:

• get/set: ops can reach 11000+ (process such redis commands in a second.), set takes average 1.5ms and get takes average 1.8ms.
• lists: ops only can reach 4500+, lpush takes average 4.5ms and get takes average 7ms

Thanks for the idea and code from https://github.com/dotcloud/go-redis-server
