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.

Features

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).
Easy to embed in Golang application.
Replication to guarantee data safe.
Supplies tools to load, dump, repair database.

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.

LedisDB supplies a simple shell to install leveldb and snappy:
```
  sh build_leveldb.sh
```
It will default install leveldb at /usr/local/leveldb and snappy at /usr/local/snappy
Set LEVELDB_DIR and SNAPPY_DIR to the actual 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

Set slaveof in config or dynamiclly

ledis-cli -p 6381 

ledis 127.0.0.1:6381> slaveof 127.0.0.1:6380
OK
