Can't optimize innoDB table

Question

As my first message here, i don't know if i have to answer or post a new message. I have the same problem as here and the one and only given answer doesn't help me (except if the documentation is incorrect). "You can make OPTIMIZE TABLE work on other storage engines", but my engine is InnoDB. I thank you for your help. S.

Answer 1

OPTIMIZE TABLE works fine on InnoDB tables. The message that says "Table does not support optimize, doing recreate + analyze instead" is purely informational. You can safely ignore that message.

Answer 2

你不能忽视结果......这意味着它做了非常密集的操作而不是轻松的操作...一个非常大的表（> 100G）这可能是几小时而不是几分钟。

Answer 3

用这个

ALTER TABLE table ENGINE='InnoDB';
