< p > Ledisdb is a high performance NoSQL like Redis based on LevelDB written by go. It supports some advanced data structure like kv, list, hash and zset, and may be alternative for Redis.< / p >

< ul >
< li > Rich advanced data structure: KV, List, Hash, ZSet, Bit.< / li >
< li > Uses leveldb to store lots of data, over the memory limit. < / li >
< li > Supports expiration and ttl.< / li >
< li > Redis clients, like redis-cli, are supported directly.< / li >
< li > Multi client API supports, including Golang, Python, Lua(Openresty). < / li >
< li > Easily to embed in Golang application. < / li >
< li > Replication to guarantee data safe.< / li >
