 StackExchange.Redis的使用经验

1、对于与Redis连接的配置，写法很宽松，最简单的写法写个IP和端口就可以了，如果有特殊配置，可以参考：https://github.com/StackExchange/StackExchange.Redis/blob/master/Docs/Configuration.md

 

2、StackExchange.Redis中的核心是ConnectionMultiplexer，可以好好研究。

 

3、在StackExchange.Redis没必要多New链接：ConnectionMultiplexer.Connect，New多个链接反而会报错，ConnectionMultiplexer内部有自己的一套调度方法。粗略的大致看作者的GitHub主页，StackExchage最多与Redis客户端建立6个连接。比较深入的，暂时吃不动。。。就以上这些了
