This just isn't that hard. They don't have that much data. It is really late for me, but, put it all in memory and figure it out. These just aren't hard problems. DBAs have been solving performance issues for decades with a clever index on the right column for 30+ years. Sorry if this is get off my lawn-ish, but I have been on too many projects where I made a DB index and solved a major bottleneck. Too many new developers are ignorant to the nuance of RDBMS tuning. I am not even a DBA.
