Brian Hulette commented on BEAM-10308:
--------------------------------------
It looks like the Java expansion client will run into the same issue. It also
uses a fresh instance of SdkComponents which is completely separate from the
instance used in PipelineTranslation, so its possible the two instances will
generate different component ids.
> Component id assignement is not consistent across PipelineContext instances

> Key: BEAM-10308

> Project: Beam
> Issue Type: Bug
> Components: cross-language, sdk-py-core
> Reporter: Brian Hulette
> Assignee: Brian Hulette
> Priority: P1

> The "unique ref" ids used in PipelineContext are generated on the fly, which
> can cause us to get a different id for the same component in different
> contexts.
> This becomes a problem when ExternalTransform is used, because it creates its
> own pipeline context for expansion. So its possible the component ids in the
> expansion request will actually refer to an entirely different component when
> the pipeline is finally assembled for execution.
