I would like to count running totals for events coming in since a given date for a given user. How would I go about doing this?
For example, we have user data coming in, we'd like to score that data, then keep running totals on that score, since a given date. Specifically, I always want to score the data, but I only want to keep a running total if the date is after a certain date (this would probably have to be looked up each time data is scored).
