    Description

      Full design doc here

      • Add a new message, RateUpdate(newRate: Long) that ReceiverSupervisor handles in its endpoint
      • Add a new method to ReceiverTracker
        def sendRateUpdate(streamId: Int, newRate: Long): Unit
        this method sends an asynchronous RateUpdate message to the receiver supervisor corresponding to streamId
      • update the rate in the corresponding block generator.
