Erik Johnston	85d237eba7	Add a distributed lock (#10269 ) This adds a simple best effort locking mechanism that works cross workers.	2021-06-29 19:15:47 +01:00
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
