----------------------------------
Summary: The user configured max parallelism does not take effect
when using adaptive batch scheduler
Key: FLINK-30917
URL: https://issues.apache.org/jira/browse/FLINK-30917
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Reporter: Lijie Wang
Fix For: 1.17.0
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.
