qiunan updated FLINK-26351:
---------------------------
Description:
In the code，flink web ui graph data from AdaptiveScheduler.requestJob()
{code:java}
@Override
public ExecutionGraphInfo requestJob() {
return new ExecutionGraphInfo(state.getJob(),
exceptionHistory.toArrayList());
} {code}
This executionGraphInfo is task restart build and restore to state.
AdaptiveScheduler.createExecutionGraphWithAvailableResourcesAsync().
You can see the jobGraph parallelism recalculate.
{code:java}
vertexParallelism = determineParallelism(slotAllocator);
JobGraph adjustedJobGraph = jobInformation.copyJobGraph();
for (JobVertex vertex : adjustedJobGraph.getVertices()) {
JobVertexID id = vertex.getID();
// use the determined "available parallelism" to use
// the resources we have access to
vertex.setParallelism(vertexParallelism.getParallelism(id));
}{code}
