> Minimize the explosion range during failover for hybrid shuffle

> Key: FLINK-28701
> URL: https://issues.apache.org/jira/browse/FLINK-28701
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.16.0
> Reporter: Weijie Guo
> Assignee: Weijie Guo
> Priority: Major
>
> In hybrid shuffle mode, there are currently two strategies to control
> spilling. For the full spilling strategy, the data is guaranteed to be
> persistent to the disk after task finished. When a failover occurs, if the
> upstream has been finished, the data should be recovered directly from the
> disk file without re-compute. For selective spilling strategy, the entire
> topology must be restarted.
