MySQL 已经或者即将跟 IBM 发生关系?

不不不,这只跟 MySQL 有关系,跟 IBM 要收购 SUN 的消息没有任何关系。

如果你下载了 MySQL 5.1.33 ,就会发现这么一个子目录 storage/ibmdb2i 。很明显这是跟 IBM 的 DB2 数据库有很大的关系。而在 5.1.33 的发布新闻中并没有提及这个问题。

进入 MySQL 的源码中有下面这么一段:

MYSQL_STORAGE_ENGINE([ibmdb2i], [], [IBM DB2 for i Storage Engine],
    [IBM DB2 for i Storage Engine], [max,max-no-ndb])
MYSQL_PLUGIN_DYNAMIC([ibmdb2i], [ha_ibmdb2i.la])

相关的注释是:

这个可能是两年前发布的 "MySQL AB and IBM Announce Open Source Database Support for the IBM System i Platform" 的结果吧。他们花了很长时间把这个整合进源码中,不知道这个将对产品带来何种有意思的变化。

希望将来mysql不要真变得和db2那家伙一样就好了,虽然现在已经很臃肿了。
