2021-05-07Do not populate AccountSummaries and FollowRecommendation views on migration ↵Claire
(#16173) Materializing those views can take a while, and they are currently refreshed anyway each time they are actually used, in the FollowRecommendationsScheduler.
2021-05-05Improve performance of follow recommendation scheduler (#16159)Claire
Express follow_recommendations in terms of account_summaries rather than accounts, integrate filters that are unconditionally used, and materialize the resulting view. This should result in the bulk of the computation being performed only once instead of **once per recommendation language**.
