My table "video" keep update and insert quite often.(viewed_time will update when user view a video)
And today, all the viewed_time have been changed, it decreased a lot.(for example, it's supposed to 10000,now it's only 100)
And I can see it says overhead in phpMyAdmin.
Also I just notice the type of the table is innodb whereas others are myisam.
That's scary! Since the viewed_time is not so important, if it's some critical data, that's disaster!
