Tzu-Li (Gordon) Tai updated FLINK-5716:
---------------------------------------
Component/s: DataStream API
> Make streaming SourceContexts aware of source idleness
> ------------------------------------------------------
>
> Key: FLINK-5716
> URL: https://issues.apache.org/jira/browse/FLINK-5716
> Project: Flink
> Issue Type: Sub-task
> Components: DataStream API, Streaming
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
>
> This task comes after FLINK-5017, which adds the new element {{StreamStatus}}
> to be incorporated with watermark progression logic.
> This task tracks the implementation of source idleness awareness and status
> toggling in {{SourceFunction.SourceContext}}s.
> The source contexts should work on an "idle interval", where we determine the
> containing {{SourceStreamTask}} to be idle if no new records / watermarks
> have been collected in-between 2 continuous checks. (default value is 0.
> Letting this value be user configurable is tracked by FLINK-5018).
