Add event_stream_ordering column to membership state tables #14979

@Fizzadar Fizzadar commented Feb 3, 2023

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 #13703 which has been a significant improvement on our database instance, suspect once applied this will be far greater.

Pull Request Checklist

Specifically this adds the 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.

This disambiguates the query. Unfortunately it means that old old Synapses (without this code change) will fail to run this query against an upgraded database.

Not sure how we should handle this.

This probably should have defined an ordering, right now it jumped ahead of all the other pending updates which seems not great.

A backwards-compatible piece of #14979 that's safe to land now.
