Full review (do not merge)

Maybe if we can do per-day basis that is fine? Not sure if we want to do per-database queries. We don't have this yet.

I think we should send this to the list maybe and dicususs what is the best approach? We want to find the best threadhold between managebility and usability.

That's the goal of SQL language, yes :-) SQL engine can collect the numbers way more faster than doing it in the application.
