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.

Argh can't believe I missed this! @DMRobertson I think this should be bumping the compat version now? Once this is applied the schema cannot be rolled back before 74. 6901682 |

Err, I think I got SCHEMA_VERSION and SCHEMA_COMPAT_VERSION mixed up. I also completely forgot about #15036. (It seems the local branch I used to generate that link is a little out of date 🤦)
Agreed: as of this change, Synapse needs to make disambiguated queries. |

Reintroduces #14979 with fixes per #15014.
Original description:
This adds an
event_stream_orderingcolumn tocurrent_state_events,local_current_membershipandroom_memberships. Each of these tables is regularly joined with theeventstable 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 thepushed back for now.eventstableSame idea as #13703 which has been a significant improvement on our database instance, suspect once applied this will be far greater.
