Re: Thoughts on partitioning by hour - and which partition type?

Hmmm,

One slight issue that has just cropped up.
Due to the poor performance of counting rows on an InnoDB table, I was maintining row counts in a separate table using triggers on the insert and deletion of records in the events table. The counts are based upon site_id.

Obviously dropping a partition doesn't cause the triggers to fire, so I guess that when I archive an existing partition I'm going to have to perform some counts in order to update my counts table before dropping the partition.
