dawidwys opened a new pull request #10417: [FLINK-14910][datastream] Checking for auto generated uids only for PhysicalStreamTransformations URL: https://github.com/apache/flink/pull/10417 ## What is the purpose of the change This PR enables the check for auto generated uids only for `PhysicalStreamTransformations`, as those are the only `StreamTransformations` that will produce a `StreamOperator` that can have a state. This solves the problem that it is not possible to assign the uid for some of the non-physical transformations (e.g `keyBy`, `split`). ## Verifying this change Added: `org.apache.flink.streaming.graph.StreamingJobGraphGeneratorNodeHashTest#testDisablingAutoUidsWorksWithKeyBy` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
