Description Bill Peck 2010-04-20 11:36:07 EDT
Description of problem:

I've seen queries on the key/value table that end up doing 20 self joins which mysql doesn't handle well.

Couple things to try here.

1 - Identify possibly problem queries, count the number of joins being built and fail if the joins are over a configured limit.

2 - Implement a timeout so that we don't wait forever on a query.

The Search could be a problem in this regard. By adding more criteria to the search they can ramp up the query to their hearts content pretty much.
Comment 2 Bill Peck 2010-04-29 14:52:32 EDT
since the query plan has been updated this doesn't seem like a problem anymore.
