             Summary: Need option to run pipeline without stable unique names
                 Key: BEAM-2438
                 URL: https://issues.apache.org/jira/browse/BEAM-2438
             Project: Beam
          Issue Type: Bug
          Components: beam-model-runner-api
            Reporter: Jonathan Bingham
            Assignee: Kenneth Knowles
            Priority: Critical


SUMMARY
When a PTransform does not have a stable unique name, the python DirectRunner raises a RuntimeError that prevents pipeline execution. In the Java SDK, this is a warning by default, which allows the pipeline to run.

OBSERVED
RuntimeError: Transform XYZ does not have a stable unique label. This will prevent updating of pipelines. To apply a transform with a specified label write pvalue | "label" >> transform

EXPECTED
Documented way to change from RuntimeError to warning, or a documented workaround.

NOTES
This is a blocker for my project, since I'm dynamically constructing a pipeline graph at runtime. I'm porting from Java, where it works by default with just a warning message, to Python, where it raises a runtime error and can't proceed.
