Richard van der Hoff	b4b2fd2ece	add a cache to have_seen_event (#9953) ... Empirically, this helped my server considerably when handling gaps in Matrix HQ. The problem was that we would repeatedly call have_seen_events for the same set of (50K or so) auth_events, each of which would take many minutes to complete, even though it's only an index scan.	2021-06-01 12:04:47 +01:00
