Drop some unused tables. (#5893)
These tables are never used, so we may as well drop them.

bf4db42920 Don't unnecessarily block notifying of new events.
When persisting events we calculate new stream orderings up front.
Before we notify about an event all events with lower stream orderings
must have finished being persisted.

This PR moves the assignment of stream ordering till *after* calculated
the new current state and split the batch of events into separate chunks
for persistence. This means that if it takes a long time to calculate
new current state then it will not block events in other rooms being
notified about.

This should help reduce some global pauses in the events stream which
can last for tens of seconds (if not longer), caused by some
particularly expensive state resolutions.

6de09e07a6 Add membership column to current_state_events table.
It turns out that doing a join is surprisingly expensive for the DB to
do when room_membership table is larger than the disk cache.

Of new events being persisted add metrics for total size of forward
extremities and number of unchanged, "stale" extremities.

d79c9994f4 Add DB bg update to cleanup extremities.
Due to #5269 we may have extremities in our DB that we shouldn't have,
so lets add a cleanup task such to remove those.

Correctly filter out extremities with soft failed prevs (#5274)
When we receive a soft failed event we, correctly, *do not* update the
forward extremity table with the event. However, if we later receive an
event that references the soft failed event we then need to remove the
soft failed events prev events from the forward extremities table,
otherwise we just build up forward extremities.

Fixes #5269

Exclude soft-failed events from fwd-extremity candidates. (#5146)
When considering the candidates to be forward-extremities, we must exclude soft
failures.

Hopefully fixes #5090.

Fix sync bug when accepting invites (#4956)
Hopefully this time we really will fix #4422.

We need to make sure that the cache on
`get_rooms_for_user_with_stream_ordering` is invalidated *before* the
SyncHandler is notified for the new events, and we can now do so reliably via
the `events` stream.

The `prev_state` field on events is not specced and so synapse shouldn't
explode if an event is missing the field.

a9b5ea6fc1 Batch cache invalidation over replication
Currently whenever the current state changes in a room invalidate a lot
of caches, which cause *a lot* of traffic over replication. Instead,
lets batch up all those invalidations and send a single poke down
the replication streams.

Hopefully this will reduce load on the master process by substantially
reducing traffic.

c5a296b10c Add support for persisting event format versions
Currently we only have the one event format version defined, but this
adds the necessary infrastructure to persist and fetch the format
versions alongside the events.

We specify the format version rather than the room version as:

1. We don't necessarily know the room version, existing events may be
   either v1 or v2.
2. We'd need to be careful to prevent/handle correctly if different
   events in the same room reported to be of different versions, which
   sounds annoying.

25dd56ace3 Fix race when persisting create event (#4404)
* Fix race when persisting create event

When persisting a chunk of DAG it is sometimes requried to do a state
resolution, which requires knowledge of the room version. If this
happens while we're persisting the create event then we need to use that
event rather than attempting to look it up in the database.

Refactor state group lookup to reduce DB hits (#4011)
Currently when fetching state groups from the data store we make two
hits two the database: once for members and once for non-members (unless
request is filtered to one or the other). This adds needless load to the
datbase, so this PR refactors the lookup to make only a single database
hit.
