-----------------------------------
Summary: 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: 1.14.3, 1.15.0
Reporter: Fabian Paul
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.
