Re: Query causing CPU Spike to 100% after MYSQL upgrade

I don't see anything in the 5.7.19-5.7.20 change list that would make such a difference.

The query cross joins cct with cfit, ie it will return every logically possible combination of cct and cfit rows. Is that intentional?

Explicit join syntax (a join b on a.x=b.y) is much easier to read, debug, maintain.
