---------------------------------------
Let's keep the names.
> Revisit Runner API PCollection unique_name
> ------------------------------------------
>
> Key: BEAM-1933
> URL: https://issues.apache.org/jira/browse/BEAM-1933
> Project: Beam
> Issue Type: Bug
> Components: beam-model-runner-api, sdk-java-core
> Reporter: Thomas Groh
> Assignee: Kenneth Knowles
> Priority: Minor
> Fix For: Not applicable
>
>
> 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"
