>             Project: Beam
>          Issue Type: Bug
>          Components: beam-model-runner-api, sdk-java-core

>            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"
