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" -- This message was sent by Atlassian JIRA (v6.3.15#6346)
