"""A federation sender that forwards things to be sent across replication to
a worker process.
It assumes there is a single worker process feeding off of it.
Each row in the replication stream consists of a type and some json, where the
types indicate whether they are presence, or edus, etc.
Ephemeral or non-event data are queued up in-memory. When the worker requests
updates since a particular point, all in-memory data since before that point is
dropped. We also expire things in the queue after 5 minutes, to ensure that a
dead worker doesn't cause the queues to grow limitlessly.
Events are replicated via a separate events stream.
