> Key: FLINK-29768
> URL: https://issues.apache.org/jira/browse/FLINK-29768
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 1.17.0
> Reporter: Weijie Guo
> Assignee: Weijie Guo
> Priority: Major
> Labels: pull-request-available
>
> At present, downstream task can be scheduled only if all upstream tasks
> finished in speculative execution mode. We can do some improvements to
> support schedule downstream tasks when the upstream's some subtask is not
> completely finished. After the upstream task's data is totally produced, we
> need to update the result partition's information of this subtask to trigger
> downstream task's consumption.
