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.

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

• Create a workspace and checkout ledisdb source

    mkdir $WORKSPACE
    cd $WORKSPACE
    git clone git@github.com:siddontang/ledisdb.git src/github.com/siddontang/ledisdb
  
    cd src/github.com/siddontang/ledisdb
  

• Install leveldb and snappy, if you have installed, skip.

  I supply a simple shell to install leveldb and snappy, you can use:

    sh build_leveldb.sh
  

  It will default install leveldb at /usr/local/leveldb and snappy at /usr/local/snappy

• Change LEVELDB_DIR and SNAPPY_DIR to real install path in dev.sh.

• Then:

    . ./bootstap.sh 
    . ./dev.sh
  
    go install ./...
  

./ledis-server -config=/etc/ledis.json

//another shell
ledis-cli -p 6380

ledis 127.0.0.1:6380> set a 1
OK
ledis 127.0.0.1:6380> get a
"1"

import "github.com/siddontang/ledisdb/ledis"
l, _ := ledis.Open(cfg)
db, _ := l.Select(0)

db.Set(key, value)

db.Get(key)

set slaveof in config or dynamiclly

ledis-cli -p 6381 

ledis 127.0.0.1:6381> slaveof 127.0.0.1:6380
OK
