You can play tricks with the arrangement of the key. For instance, you can put date at the end of the key. That would let you pull data for a particular user for a particular date range. The date should not be a time stamp, but should be a low-res version of time (day-level resolution might be ok) so that you can minimize number of rows.
hi Ted i do not see any way to put the date into the row key, there are many requests/impressions for a particular user (row key) so no chance to put a date into the key andre
