现在遇到个情况~主从同步中从库老是会有慢查询日志
在从库上

比方有1000个人运行了这个程序

总会有那么几个需要2秒运行时间而其他人都是秒杀..

请问这类情况大家遇到过吗

...

我也想过是不是当时并发执行其他程序导致那个时间段的那么几个人运行受到影响...

但是还是不怎么能接受...

------解决方案--------------------
这很正常
有可能正在查询的时候系统比较繁忙所以记录了
如果语句本身没问题还是可以接受的

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
