pika可以直接使用redis的客户端。
目前我们线上常见的用法的一主多从+读写分离来扩展，这样的方式写入依旧是单点，不过也可以通过给pika上层挂codis来进行分片。目前我们还没有1pb的线上使用场景，这个需要验证。

不太明白。 主从的意思是replica吗？ 也就是说这个项目并不支持分布式？

你们现在有支持到的最大数据量是多少呢？

嗯，pika的定位就是在功能上接近3.0之前的redis（不支持cluster，仅支持通过slaveof来做主从），目前我们公司内部没有给pika挂codis做分片，单实例最大在2T左右

明白了。 麻烦能贴下你们2T时的主机配置吗？ 我觉得分布式必不可少啊，后期会不会加上这些功能呢？

暂时还没有支持分片的计划，你可以先挂codis来实现
