性能.
InnoDb 提供自己的缓存(buffer pool) 还缓存数据和索引.innodb 把数据和索引存放
到表空间(tablespace) ,表空间是多个 硬盘 文件或者是原是设备文件(raw disk). 它
不像MyISAM 存储引擎,每个表只是一个文件.(这样在某些系统下最大2G限定 ). 而Innodb
没有此限定 ,可以无限扩展.
Mysql4.0 的以后版本都支持innodb 存储.
如果你的MySQL不支持InnoDB存储引擎，请按照如下的步骤执行 修改。
1.关上 MySQL数据库
2.修改my.ini文件，把skip-innodb这行注释掉
3.打开MySQL数据库
即可。
