Subject [jira] [Created] (BEAM-1933) Revisit Runner API PCollection unique_name
Date Tue, 11 Apr 2017 17:52:41 GMT
Thomas Groh created BEAM-1933:

             Summary: Revisit Runner API PCollection unique_name
                 Key: BEAM-1933
             Project: Beam
          Issue Type: Bug
          Components: beam-model-runner-api, sdk-java-core
            Reporter: Thomas Groh
            Assignee: Kenneth Knowles
            Priority: Minor

The Java SDK performs no work to ensure that a PCollection has a unique name. Most names will
end up being unique, because they are autogenerated based on the full name of the producing
transform, but names can be set by users arbitrarily.

We can generate a unique name, potentially one based on the PCollection name, but this may
not map to something that is "stable over multiple evolutions of a pipeline"
