godfreyhe opened a new pull request #14757: URL: https://github.com/apache/flink/pull/14757
## What is the purpose of the change *Currently, the ExecEdge represents the properties for the input of an operator, the properties include 1. required data distribute for an input (the input corresponds to the [Input](https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/operators/Input.java)) 2. DamBehavior which describes the behaviors how an in record may trigger the output of the target operator. 3. the priority of this input read by the target operator So ExecEdge should be rename to InputProperty, and we will re-introduce ExecEdge which describes how to connect two ExecNodes in FLINK-21150, and how to shuffle the data between two ExecNodes. Its role should be similar to StreamEdge.* ## Brief change log - *Rename ExecEdge to InputProperty* - *rename RequiredShuffle to RequiredDistribution* ## Verifying this change This change is a refactoring rework covered by existing tests. ## 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?
