Thesharing opened a new pull request #15088: URL: https://github.com/apache/flink/pull/15088
## What is the purpose of the change *This PR introduces the optimization of the initialization of DefaultExecutionTopology.* *Based on FLINK-21326, the consumedResults in DefaultExecutionVertex and consumers in DefaultResultPartition can be replaced with ConsumedPartitionGroup and ConsumerVertexGroup in EdgeManager. The complexity of initializing DefaultExecutionTopology decreases from O(N^2) to O(N).* *For more details, please check [FLINK-21328](https://issues.apache.org/jira/browse/FLINK-21326).* ## Brief change log - *Remove generic from LogicalTopology and its components* - *Transform Vertex#getConsumedResults to LogicalVertex#getConsumedResults and SchedulingExecutionVertex#getGroupedConsumedResults* - *Transform Result#getConsumers to LogicalResult#getConsumers and SchedulingResultPartition#getGroupedConsumers* - *Remove DefaultExecutionTopology#connectVerticesToConsumedPartitions, and replace connections between DefaultExecutionVertices and DefaultResultPartitions with connections stored in EdgeManager* ## Verifying this change *Since these optimizations do not change the original logic of the establishing connections in DefaultExecutionTopology, we believe that this change is already covered by existing tests, such as DefaultExecutionTopologyTest, DefaultExecutionVertexTest, DefaultResultPartitionTest, DefaultSchedulingPipelinedRegionTest, and etc.* ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: (**yes** / no / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
