Sean Quah	c675a18071	Track ongoing event fetches correctly (again) (#11376) ... The previous fix for the ongoing event fetches counter (8eec25a1d9) was both insufficient and incorrect. When the database is unreachable, `_do_fetch` never gets run and so `_event_fetch_ongoing` is never decremented. The previous fix also moved the `_event_fetch_ongoing` decrement outside of the `_event_fetch_lock` which allowed race conditions to corrupt the counter.	2021-11-26 13:47:24 +00:00

Erik Johnston	c37dad67ab	Improve event caching code (#10119) ... Ensure we only load an event from the DB once when the same event is requested multiple times at once.	2021-08-04 13:54:51 +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
