If you have InnoDB file per table enabled, dropping the older partitions actually helps to keep disk space in check. We have been using this method for a while successfully with that goal in mind.It’s a trick I learned while working at Pythian :)

Giuseppe — that *is* great! It wasn’t on my radar because I wasn’t even thinking about using partitions back then (IIRC that was about 1 month after 5.1 was GA’d).

If you need to add many partitions, the task could be made easier by the Partition Helper:
