Work Description: youngoli commented on pull request #13255:
URL: https://github.com/apache/beam/pull/13255#issuecomment-722125473
Actually don't merge this yet. I ran into an issue where adding a scope
(i.e. putting the external transform in a composite) causes all the examples to
fail. It seems to be because of a built-in assumption in the cross-language
code that the root transform of the protobuf external transform is the external
transform itself, but this is false when it's in a composite, because the root
transform is the composite instead.
I'm still trying to fix that, because this is an issue that would give users
trouble immediately and needs to be fixed ASAP. That said, if the rest of the
PR looks good I might just comment out the Scope calls with a TODO and a Jira,
since that will work.

> Key: BEAM-11188
> URL: https://issues.apache.org/jira/browse/BEAM-11188
> Project: Beam
> Issue Type: Improvement
> Components: cross-language, sdk-go
> Reporter: Daniel Oliveira
> Assignee: Daniel Oliveira
> Priority: P2
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> This is a bug for progress on various small usability and UX improvements to
> the Go SDK implementation of Cross-Language. I don't feel each one
> individually is important enough for a Jira, but together it's worth
> recording progress.
> Tasks included:
> * Adjust user-facing XLang functions so that Sink and Source versions are
> actually sinks and sources (no outputs and no inputs respectively).
> * Rename SourceInputTag and SinkOutputTag since they are no longer used with
> source/sink versions of the methods.
> * Adjust beam/xlang.go so that it doesn't need to import job_management
> protos. Move the proto creation down into the method the proto is passed to
> (which is xlangx.Expand).
> * Refactor the functions in xlangx/translate.go and how they are used, since
> right now the functions just get called one after another in sequence.
> * Move as many xlang calls out of universal.go as possible. They should be
> handled as part of the normal sequence of the SDK, such as in proto
> marshalling and unmarshalling.
> * Add wrappers around xlang calls in existing examples, to both give a
> cleaner interface and provide an example of how xlang transforms should be
> implemented.
