Stephan Ewen commented on FLINK-5018:
-------------------------------------

I think we can close this issue. This should be subsumed by the new source interface and the new watermark generators.

> There are 2 cases where sources are considered idle and should emit an idle {{StreamStatus}} downstream, taking Kafka consumer as example:
> - The source instance was not assigned any partitions
> - The source instance was assigned partitions, but they currently don't have any data.
> For the second case, we can only consider it idle after a timeout threshold. It would be good to make this timeout user configurable besides a default value.
