简介
MySQL 作为最流行的开源数据库，在各个领域都有相当广泛的应用，作为一个 MySQL DBA，经常会对数据库进行一些性能测试来主动（或者是被动的）对业务压力做一个评估，来判断数据库当前的负载以及最高的性能容量。
常见的性能测试工具有 sysbench 和 tpcc，这两者都是非常优秀的压测工具，但是都需要特殊的编译或者安装，并且需要一定的开发能力才能修改具体测试的语句。
mysqlslap 则是随着 MySQL 安装的时候就自动安装好了，而且 mysqlslap 把很多的自定义测试的功能封装到了外部，使用者只需要在外部提供 SQL 语句的脚本就可以自定义测试语句，使用起来会简便一些。
使用介绍
mysqlslap 提供了非常多的参数来配置测试的项目的类型，这里仅摘选部分常用参数进行说明，详细信息参考 mysqlslap 自身的帮助信息。
