文章网址: 执行一条 select 语句,期间发生了什么? 具体错误: SQL语法树的构建应该是语法分析阶段的任务, 文中错把其归类到词法分析下

我这也补充一个疑问,文中提到Mysql 8.0把查询缓存去掉了,但我看官方内存模型里还是有个buffer pool,也是缓存查询用的,这个是不是有误?https://dev.mysql.com/doc/refman/8.0/en/innodb-buffer-pool.html
Sorry, something went wrong.
@hcldadi 这里说的查询缓存是 server 层的,也就是 MySQL 8.0 版本移除的是 server 层的查询缓存,并不是 Innodb 存储引擎中的 buffer poll。
