[jira] [Created] (FLINK-5716) Make streaming SourceContexts aware
of source idleness
Tzu-Li (Gordon) Tai created FLINK-5716:
------------------------------------------
Summary: 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: 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).
