Re: Data not balanced in partitions

PARTITION BY KEY uses a very simple hash. Even if the key is random enough, the partitions will rarely be "perfectly" balanced.

How many rows do you expect when the table is filled?

Why do this PARTITIONing? This is a serious question. I can't think of any performance benefit. I can't think of any coding benefit. Or any other benefit.
