From 5fdc12f482c68e2cdbb78d7db5de2cfe621720d4 Mon Sep 17 00:00:00 2001 From: Nick Mills-Barrett Date: Tue, 7 Feb 2023 01:10:54 +0100 Subject: Add `event_stream_ordering` column to membership state tables (#14979) This adds an `event_stream_ordering` column to `current_state_events`, `local_current_membership` and `room_memberships`. Each of these tables is regularly joined with the `events` table to get the stream ordering and denormalising this into each table will yield significant query performance improvements once used. Includes a background job to populate these values from the `events` table. Same idea as https://github.com/matrix-org/synapse/pull/13703.
