---------------------------
Resolution: Duplicate
> Improve attachJobGraph Performance
> ----------------------------------
>
> Key: FLINK-16017
> URL: https://issues.apache.org/jira/browse/FLINK-16017
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.10.0
> Reporter: Jiayi Liao
> Priority: Major
>
> Currently {{RegionPartitionReleaseStrategy}} and {{AdaptedRestartPipelinedRegionStrategyNG}} both need to compute distinct pipelined regions, which affects the performance due to the duplicate calculating.
> The best idea that comes to my mind so far is calculating distinct pipelined regions in {{DefaultExecutionTopology}} so that we can remove the duplicate calculating.
