Re: Size of partition table space

In your example, about 10% of the disk space is "wasted" by the "free" space. This is not that big a deal. And it is a small price to pay for what is probably a performance gain (by having the the free space already available).

Space is not the big deal in PARTITIONing; picking the right partition method for your application is.

I cannot imagine why having a particular number of rows in a partition would matter.

As for space taken before DELETEing, there is no much you can do.

Space recovery after a DELETE -- the best way is via DROP PARTITION, as I already mentioned. But that requires you to design the PARTITION method to match the DELETEs.
