> Currently the purge requests are sent to the buffer servers from the app
> master. This interaction exists parallel to the heartbeat protocol. Instead,
> the committed window ID that is propagated through the heartbeat response can
> be used in StreamingContainer to initiate the purge with the local buffer
> server, similar to how the committed callback on the operator occurs.
