# 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. LedisDB use the modified LevelDB for better performance, see [here](https://github.com/siddontang/ledisdb/wiki/leveldb-source-modification). + Set LEVELDB_DIR and SNAPPY_DIR to the actual install path in dev.sh. + Then: . ./bootstap.sh . ./dev.sh go install ./... ## Server Example ./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" ## Package Example import "github.com/siddontang/ledisdb/ledis" l, _ := ledis.Open(cfg) db, _ := l.Select(0) db.Set(key, value) db.Get(key) ## Replication Example Set slaveof in config or dynamiclly ledis-cli -p 6381 ledis 127.0.0.1:6381> slaveof 127.0.0.1:6380 OK ## Benchmark See benchmark.md for more. ## Todo See [Issues todo](https://github.com/siddontang/ledisdb/issues?labels=todo&page=1&state=open) ## Links + [Official Website](http://ledisdb.com) + [Author's Chinese Blog](http://blog.csdn.net/siddontang/article/category/2264003) + [GoDoc](https://godoc.org/github.com/siddontang/ledisdb) + [Server Commands](https://github.com/siddontang/ledisdb/wiki/Commands) ## Thanks Gmail: cenqichao@gmail.com Gmail: chendahui007@gmail.com Gmail: cppgohan@gmail.com Gmail: tiaotiaoyly@gmail.com Gmail: wyk4true@gmail.com ## Feedback Gmail: siddontang@gmail.com
