redis的一些tips

这是我计划本周五在部门内分享的内容，先贴到这里：

Redis是一款最近比较热门的Key-value数据库，它的代码量少，配置简单，与memcache同样轻量级，对于了解NoSQL是一个很好的入口，相信通过介绍之后，无论是前端和后端开发工程师，都会迅速的爱上这款软件！

    * Features:
          o Key-value db
          o Fast: all data are loaded in memory and saved on disk
          o Supporting data types: Strings(<1Gb), Lists, Hashes, Sets, Ordered sets.
          o Interfaces: push/pop、add/remove、sort
          o Replication:
                + 一个master支持多个slave
                + Slave可以接受其他slave的连接来替代他连接master
                + 复制在master是非阻塞的，而在slave是阻塞的
                + 复制被利用来提供可扩展性，在slave端只提供查询功能及数据的冗余
