  -- We don't declare a foreign key on stream_ordering here because that'd mean
  -- we'd need to either maintain an index (expensive) or do a table scan of
  -- destination_rooms whenever we delete an event (also potentially expensive).
  -- In addition to that, a foreign key on stream_ordering would be redundant
  -- as this row doesn't need to refer to a specific event; if the event gets
  -- deleted then it doesn't affect the validity of the stream_ordering here.
