MySQL8.0自带工具ibd2sdi解析ibd文件
ibd文件是mysql的表数据文件，在mysql8之前数据表里的表定义放在xxx.frm文件中，表数据和表索引放在.ibd文件中。都在mysql的data目录下的数据库名所在目录下。不知道自己data目录在哪里的在数据库执行show variables like ‘%datadir%’ 查看路径
将MySQL8.0的bin路径加入系统环境变量path里（C:\Program Files\MySQL\MySQL Server 8.0\bin）
进入mysql数据文件目录C:\ProgramData\MySQL\MySQL Server 8.0\Data\test>
找到自己的表的ibd文件
在当前目录打开cmd
执行命令解析
ibd2sdi --dump-file member.txt member.ibd
查看解析后的txt文件，我们可以看到8.0版本的mysql把表结构、索引全部都放到了表数据文件ibd文件中了
