LedisDB

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.

Build and Install

• 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 ./...
  

Run

./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"

Lib

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

db.Set(key, value)

db.Get(key)

Replication

ledis-cli -p 6381 

ledis 127.0.0.1:6381> slaveof 127.0.0.1:6380
