Currently, the entirety of incremental dumps is checked to filter entities whose stats/popularity needs to be recomputed. This can be further optimized by storing the latest created timestamp of the listens in incremental dumps when a stat is run. The next time a stat is run, only listens with a higher created value (added through newer incremental dumps) are considered for the filter. Note that the incremental aggregate is still computed from all of incremental listens dump, only the filter is made more granular.
