the fundamental problem with counters is that it does a read-modify-write cycle which is quite harsh on the DB - a better approach is to take advantage that counters are cumulative and we can keep the delta events only and 'merge' them on reads

or just buffer the counters in redis and then flush them out

I have a counters API that does precisely this
