Re: not optimizing the table after index is created

OPTIMIZE TABLE is useful for MyISAM. For compatibility, it exists for InnoDB, but is implemented using other commands. OPTIMIZE table is virtually useless for InnoDB. It is not needed after adding an index (or any other ALTER) since the intent of OPTIMIZE has already been performed by that action.

What did you do? CREATE INDEX? ALTER TABLE ADD INDEX?

Please provide SHOW CREATE TABLE.
