[GitHub] [flink] wanglijie95 opened a new pull request, #21928: [FLINK-30917][runtime] Let adaptive batch scheduler also respect the user-configured max parallelism when deciding parallelism

wanglijie95 opened a new pull request, #21928:
URL: https://github.com/apache/flink/pull/21928

   ## 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`
