ssdb是一个快速的用来存储十亿级别列表数据的开源 nosql 数据库。项目地址：https://github.com/ideawu/ssdbhttp://ssdb.io/特性替代 redis 数据库, redis 的 100 倍容量 leveldb 网络支持, 使用 c/c++ 开发 redis api 兼容, 支持 redis 客户端 适合存储集合数据, 如 list, hash, zset... 客户端 api 支持的语言包括: c++、php、python、cpy、java、nodejs、ruby、go。 持久化的队列服务 主从复制, 负载均衡性能1000请求：writeseq : 0.546 ms/op 178.7 mb/swriterand : 0.519 ms/op 188.1 mb/sreadseq : 0.304 ms/op 321.6 mb/sreadrand : 0.310 ms/op 315.0 mb/s

在macbook pro 13 （retina屏幕）上运行。与redis的比较：性能数据使用 ssdb-bench(ssdb) 和 redis-benchmark(redis) 来获取。架构安装下载压缩包，解压缩wget --no-check-certificate https://github.com/ideawu/ssdb/archive/master.zipunzip mastercd ssdb-master
编译make
安装（可选）sudo make install
运行./ssdb-server ssdb.conf
或者以后台的方式运行./ssdb-server -d ssdb.conf
ssdb命令行./tools/ssdb-cli -p 8888
停止ssdb-serverkill `cat ./var/ssdb.pid`
使用phpgetmessage());}$ret = $ssdb->set('key', 'value');if($ret === false){ // error!}echo $ssdb->get('key');
python使用pyssdb>>> import pyssdb>>> c = pyssdb.client()>>> c.set('key', 'value')1>>> c.get('key')'value'>>> c.hset('hash', 'item', 'value')1>>> c.hget('hash', 'item')'value'>>> c.hget('hash', 'not exist') is nonetrue>>> c.incr('counter')1>>> c.incr('counter')2>>> c.incr('counter')3>>> c.keys('a', 'z', 1)['counter']>>> c.keys('a', 'z', 10)['counter', 'key']
ruby使用ssdb-rbrequire ssdbssdb = ssdb.new url: ssdb://1.2.3.4:8889ssdb.set(mykey, hello world)# => truessdb.get(mykey)# => hello worldssdb.batch do ssdb.set foo, 5 ssdb.get foo ssdb.incr fooend# => [true, 5, 6]
