improve performance saving stories from feed. In the case where there are 500 stories that need duplicate checking, this would reduce sql to database from 1000 to 2. interested in feedback for this pr. So far tested against the small dokku feedset. I have the full 110k feeds running on a cloud server and will deploy there also.
Todo:
add an index to Stories.sources_id
batch insert of new stories into stories table?
