> When deploying tasks to a task manager it not guaranteed that all results are already consumable. In such cases, the InputGate of the receiver creates "UnknownInputChannel" instances, which are updated during runtime to Local- or RemoteInputChannel instances.
> The UpdateTask Akka message which triggers this update contains unused information (the producing task's execution attempt ID) to identify which channel to update. I found this confusing when looking over the code and actually thought that it was a bug (because the unused information was actually erroneous).
