> Operator maxParallelism is lost during chaining
> -----------------------------------------------
>
> Key: FLINK-26358
> URL: https://issues.apache.org/jira/browse/FLINK-26358
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.15.0, 1.14.3
> Reporter: Fabian Paul
> Priority: Critical
> Labels: pull-request-available, stale-critical
>
> During the generation of the JobGraph from the StreamGraph the maxParallelism
> of the chained operators is lost so the maxParallelism written to a snapshot
> might not reflect the real maxParallelism of the operator.
> If a user now unchains the operator it is not possible to restore a snapshot
> anymore because the maxParallelism of the operator and the snapshot do not
> match anymore.
