《MySQL是怎样运行的:从根儿上理解 MySQL》采用诙谐幽默的表达方式,对MySQL的底层运行原理进行了介绍,内容涵盖了使用MySQL的同学在求职面试和工作中常见的一些核心概念。总计22 章,划分为4个部分。第1部分介绍了MySQL入门的一些知识,比如MySQL的服务器程序和客户端程序有哪些、MySQL的启动选项和系统变量,以及使用的字符集等。第2部分是本书后续章节的基础,介绍了MySQL的一些基础知识,比如记录、页面、索引、表空间的结构和用法等。第3部分则与大家在工作中经常遇到的查询优化问题紧密相关,介绍了单表查询、连接查询的执行原理,MySQL基于成本和规则的优化具体指什么,并详细分析了Explain语句的执行结果。第4部分则是与MySQL中的事务和锁相关,介绍了事务概念的来源,MySQL是如何实现事务的,包括redo日志、undo日志、MVCC、各种锁的细节等。尽管《MySQL是怎样运行的:从根儿上理解 MySQL》在写作时参考的MySQL源代码版本是5.7.22,但是大部分内容与具体的版本号并没有多大关系。无论是很早之前就已身居MySQL专家的人员,还是希望进一步提升技能的DBA,甚至是三五年后才会入行的“萌新”,本书都是他们彻底了解MySQL运行原理的优秀图书。
