Add per-room rate limiting for room joins. For each room, Synapse now monitors the rate of join events in that room, and throttle additional joins if that rate grows too large.

## Changes to the event replication streams
|
||||
|
||||
Synapse now includes a flag indicating if an event is an outlier when
|
||||
replicating it to other workers. This is a forwards- and backwards-incompatible
|
||||
change: v1.63 and workers cannot process events replicated by v1.64 workers, and
|
||||
vice versa.
|
||||
|
||||
Once all workers are upgraded to v1.64 (or downgraded to v1.63), event
|
||||
replication will resume as normal.

### `rc_joins_per_room`
|
||||
|
||||
This option allows admins to ratelimit joins to a room based on the number of recent
|
||||
joins (local or remote) to that room. It is intended to mitigate mass-join spam
|
||||
waves which target multiple homeservers.
|
||||
|
||||
By default, one join is permitted to a room every second, with an accumulating
|
||||
buffer of up to ten instantaneous joins.
|
||||
|
||||
Example configuration (default values):
|
||||
```yaml
|
||||
rc_joins_per_room:
|
||||
per_second: 1
|
||||
burst_count: 10
|
||||
```
|
