> 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 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.
