説明

What would you like to happen?

The Go SDK's dot runner current generates a pipeline graph based on the Go SDK internal structures.

https://github.com/apache/beam/blob/master/sdks/go/pkg/beam/core/util/dot/dot.go#L89

If it were rewritten in terms of the portable pipeline proto (https://github.com/apache/beam/blob/master/model/pipeline/src/main/proto/org/apache/beam/model/pipeline/v1/beam_runner_api.proto#L91) then it could be used to render Cross Language pipelines and be used as a basis for the stand alone Prism Runner's web UI.

That would sufficiently allow #25896 to be closed.

調査方針
Start by reviewing the current dot runner implementation at https://github.com/apache/beam/blob/master/sdks/go/pkg/beam/core/util/dot/dot.go to understand how it generates the graph. Then study the portable pipeline proto definition at https://github.com/apache/beam/blob/master/model/pipeline/src/main/proto/org/apache/beam/model/pipeline/v1/beam runner api.proto to see the new representation needed. Finally, rewrite the dot runner to use the portable pipeline proto, ensuring it can render cross language pipelines and serve as a basis for Prism Runner's web UI. This will also help close issue #25896.
