+## Introduction[中文](https://github.com/Qihoo360/pika/blob/master/README_CN.md)
 
 Pika is a persistent huge storage service , compatible  with the vast majority of redis interfaces ([details](https://github.com/Qihoo360/pika/wiki/pika-支持的redis接口及兼容情况)), including string, hash, list, zset, set and management interfaces. With the huge amount of data stored, redis may suffer for a capacity bottleneck, and pika was born for solving it. Except huge storage capacity, pika also support master-slave mode by slaveof command, including full and partial synchronization. You can alse use pika in twemproxy or codis(*pika has supported data migration in codis，thanks [left2right](https://github.com/left2right)*) for distributed Redis solution
