wanglijie95 opened a new pull request, #21861: URL: https://github.com/apache/flink/pull/21861
## What is the purpose of the change Currently, the adaptive batch scheduler only respects the global maximum parallelism(which is configured by option parallelism.default or execution.batch.adaptive.auto-parallelism.max-parallelism, see [FLINK-30686](https://issues.apache.org/jira/browse/FLINK-30686) for details) when deciding parallelism for job vertices, the maximum parallelism of vertices configured by the user through setMaxParallelism will not be respected. In this ticket, we will change the behavior so that the user-configured max parallelism also be respected. ## Verifying this change Add tests in `DefaultVertexParallelismAndInputInfosDeciderTest` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (**no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (**no**) - The serializers: (**no**) - The runtime per-record code paths (performance sensitive): (**no**) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: (**no**) - The S3 file system connector: (**no**) ## Documentation - Does this pull request introduce a new feature?
