Pixy's Actually Useful Tip Of The Day, Part Two
If you INSERT IGNORE into a MySQL table with an auto-increment primary key, the counter will increment even if the INSERT is IGNORED due to a duplicate secondary index.
And if you're abusing this process in horrible ways, you can pretty quickly wrap a 32-bit int, in which case all your INSERTS will be IGNORED.
Solution: Use a 64-bit int.
Hey, I'm not saying it's a good solution.
