             Summary: Improve the scheduling performance of 
AdaptiveBatchScheduler
                 Key: FLINK-32288
                 URL: https://issues.apache.org/jira/browse/FLINK-32288
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.18.0
            Reporter: xingbe
             Fix For: 1.18.0


After adding the benchmark of AdaptiveBatchScheduler in FLINK-30480, we noticed 
a regression in the performance of 
SchedulingDownstreamTasksInBatchJobBenchmark#SchedulingDownstreamTasks. When 
scheduling a batch job with a parallelism of 4000*4000, the time spent 
increased from 32ms to 1336ms on my local PC.

To improve the performance, we can optimize the traversal by checking if the 
consumedPartitionGroups have finished all its partitions.
