The mysql performance_schema method for counting per-database queries is very heavyweight in that it requires full logging (in a table) of every query. We do hundreds of thousands in the course of a tempest run, which ends up creating its own performance problem. This changes the approach we take, which is to bundle a very tiny sqlalchemy plugin module which counts just what we care about in a special database. It is more complex than just enabling the features in mysql, but it is a massively smaller runtime overhead. It also provides us the opportunity to easily zero the counters just before a tempest run.
