> Key: FLINK-14234
> URL: https://issues.apache.org/jira/browse/FLINK-14234
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 1.10.0
> Reporter: Zhu Zhu
> Assignee: Zhu Zhu
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.11.0
>
>
> {{SchedulingStrategy}} requires partition consumable notification to make
> scheduling decisions.
> According to {{SchedulingStrategy#onPartitionConsumable}} definition, all
> partition consumable events should be notified to {{SchedulingStrategy}},
> including those from TMs (pipelined partitions consumable for data produced)
> and from within JM(blocking partitions consumable for producer finished).
> In this way, the LazyFromSourcesSchedulingStrategy does not need to maintain
> the result partition status by itself. InputDependencyConstraintChecker can
> be simplified a lot in this way.
> Besides that, LazyFromSourcesSchedulingStrategy does not need to be aware of
> result partition types(PIPELINED/BLOCKING) in this way.
> It would also simplify the input checking for pipelined region scheduling.
> More details see
> [here|https://github.com/apache/flink/pull/9663#discussion_r326540913].
