Table does not support optimize, doing recreate + analyze instead

Everytime you do optimize MySQL, by using mysqlcheck -A -o or using ./mysql_optimize from here.
You may see the output

Table does not support optimize, doing recreate + analyze instead.

It is because the table that you are using is InnoDB.

You can optimize the InnoDB tables by using this.


ALTER TABLE table.name ENGINE='InnoDB';




This will create a copy of the original table, and drop the original table, and replace to the original place.
Although this is safe, but I suggest you do backup and test first before doing this.
