经过前三篇的讨论，我们终于的实现了“最终一致性”，那今天呢，我们再进一步，在前一个方案的基础上实现“强一致性”
强一致性，包含两种含义：
缓存和DB数据一致
缓存中没有数据（或者说：不会去读缓存中的老版本数据）
首先我们来分析一下，既然已经实现了“最终一致性”，那它和“强一致性”的区别是什么呢？没错，就是“时间差”，所以：
“最终一致性方案” + “时间差” = “强一致......

经过前两篇的讨论，我们离实现“最终一致性”只差一步了
在《缓存与数据库一致性系列-02》文章，我们提到上一个方案的并发问题
读的时候，缓存中的数据已失效，此时又发生了更新
数据更新的时候，缓存中的数据已失效，此时又发生了更新
那我们我们可以看到，这个问题就来自于“读数据库” + “写缓存” 之间的交错并发，那怎么来避免呢？有一个方法就是：串行化，我们利用MQ将所有“读数据库” + “......

在《缓存与数据库一致性系列-01》文章，我们提到，“它的一个比较大的缺陷在于刷新缓存有可能会失败，而失败之后缓存中数据就一直会处于错误状态，所以它并不能保证数据的最终一致性”
为了保证“数据最终一致性”，我们引入binlog，通过解析binlog来刷新缓存，这样即使刷新失败，依然可以进行日志回放，再次刷新缓存

今天，我们来分析一下，缓存与数据库被使用次数最多的一种使用方法
写流程：第一步先删除缓存，删除之后再更新DB，之后再异步将数据刷回缓存
读流程：第一步先读缓存，如果缓存没读到，则去读DB，之后再异步将数据刷回缓存
方案分析优点剖析1. 实现起来简单
What Should I Say ?
2. “先淘汰缓存，再写数据库” 合理为什么说这也算优点呢？试想一下

一般来说，对于一个新的业务，一般会经历这几个阶段：
阶段1：单库阶段读写流量都比较小，这个时候所有的读写操作都在主库就ok了这个时候，从库可能只是用来灾备风险分析：从数据一致性角度来说没有风险，全走主库美滋滋~
阶段2：多库阶段阶段2.1：单库扛不住了，这个时候就会考虑到分库分表了，通过增加数据库的方式，把单库的QPS降下来风险分析： 从数据一致性角度来说没有风险，全走主库依然美滋滋~
