----------------------------------
Summary: 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
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.
