[@more@]今天早上数据库slow log异常多，查了下昨天也很多，于是到监控库里面查了下

3,4号的时候，导入了大批数据库，这个点开始不足为怪，比较怪异的是出现的日期，3，4，10，11，都是周三周四，巧合还是？
细细分析了下问题出现的时间，对比对应时间，发现在对应的时间里都有binlog切换，但binlog总是在切换，为什么是这个时间出现问题呢？注意出现问题的时间基本都是早上和凌晨的。
3，4号，10，11号，突然想到了一个关键-我们线上binlog是保留7天的，由于3，4号产生了大量的binlog，在这个时间，binlog切换的时候同时触发过期binlog的清除操作，由于大量的binlog清除，加上binlog本身的切换，导致IO消耗上升与会话堆积同时出现，于是出现了这个奇怪的现象。
如果判断正确最多到明天，这样的情况就会消失了。
作为总结，在以后导入数据的时候一定要主动做个binlog清除操作，操作命令大概为Purge binlog before –time—这样吧

补充：放低SlowQ限制，这个查询也为上面的推测提供了有力的数据支持！
