Re-calculate similarities based on user similarities #25

Closed treyhunner closed 9 years ago

treyhunner commented 9 years ago

I'm not sure if this should happen on every UserSimilarity save, as a queued task shortly after saves, or as a scheduled task.

Let's keep it simple first, do it on each save. Especially if we're saving each similarity separately, it will only be averaging across those records, one query for the calculation to take place, and a second to save. Two extra queries per similarity added or modified.

@macro1 that seems fine at first
