Mysql InnoDB的概念
InnoDB给MySQL提供了具有提交，回滚和崩溃恢复能力的事务安全(ACID兼容)存储引擎。InnoDB锁定在行级并且也在SELECT语句提供一个Oracle风格一致的非锁定读。这些特色增加了多用户部署和性能。没有在InnoDB中扩大锁定的需要，因为在InnoDB中行级锁定适合非常小
InnoDB给MySQL提供了具有提交，，回滚和崩溃恢复能力的事务安全(ACID兼容)存储引擎。InnoDB锁定在行级并且也在SELECT语句提供一个Oracle风格一致的非锁定读。这些特色增加了多用户部署和性能。没有在InnoDB中扩大锁定的需要，因为在InnoDB中行级锁定适合非常小的空间。InnoDB也支持FOREIGN KEY强制。在SQL查询中，你可以自由地将InnoDB类型的表与其它MySQL的表的类型混合起来，甚至在同一个查询中也可以混合。
InnoDB是为处理巨大数据量时的最大性能设计。它的CPU效率可能是任何其它基于磁盘的关系数据库引擎所不能匹敌的。
InnoDB存储引擎被完全与MySQL服务器整合，InnoDB存储引擎为在主内存中缓存数据和索引而维持它自己的缓冲池。InnoDB存储它的表&索引在一个表空间中，表空间可以包含数个文件(或原始磁盘分区)。这与MyISAM表不同，比如在MyISAM表中每个表被存在分离的文件中。InnoDB 表可以是任何尺寸，即使在文件尺寸被限制为2GB的操作系统上。
InnoDB默认地被包含在MySQL二进制分发中。Windows Essentials installer使InnoDB成为Windows上MySQL的默认表。
InnoDB被用来在众多需要高性能的大型数据库站点上产生。著名的Internet新闻站点Slashdot.org运行在InnoDB上。Mytrix, Inc.在InnoDB上存储超过1TB的数据，还有一些其它站点在InnoDB上处理平均每秒800次插入/更新的负荷。
