---------------------------------
Fix Version/s: (was: 1.5.0)
1.5.1
> Make source idle timeout user configurable
> ------------------------------------------
>
> Key: FLINK-5018
> URL: https://issues.apache.org/jira/browse/FLINK-5018
> Project: Flink
> Issue Type: Sub-task
> Components: DataStream API
> Reporter: Tzu-Li (Gordon) Tai
> Priority: Major
> Fix For: 1.5.1
>
>
> 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.
