You know already that InnoDB in MySQL 5.5 has great improvements in performance and scalability. You will have to wait a few months for that, though, because MySQL 5.5 is not GA yet.

While I was researching for my partitions tutorial, I came across two hidden problems, which may happen often, but are somehow difficult to detect and even more difficult to fix, unless you know what's going on, and why. I presented both cases during my tutorial, but there were no pictures to convey the mechanics of the problem. Show More Summary
