Work Description: KevinGG commented on issue #10132: [BEAM-8016] Pipeline
Graph
URL: https://github.com/apache/beam/pull/10132#issuecomment-557240292
> Does this mean that non-cached PCollections will also be displayed in the
dot graph with a generated name?
If any of the non-cached PCollections belongs to an output of a top level
transform, then yes, they will be rendered as a circle with no name (we use
`label=""` to override whatever name they might have) in it.
Most of the non-cached PCollections exist in-between non-top-level
transforms (such as sub transforms of a composite transform the user defines)
as intermediate input-outputs within a composite transform. Since the DOT
doesn't support expanding composite transforms, they will not be rendered. If
in the future, we support expanding those transforms in graph, they will be
rendered as circles without names too.

> Render Beam Pipeline as DOT with Interactive Beam

> Key: BEAM-8016
> URL: https://issues.apache.org/jira/browse/BEAM-8016
> Project: Beam
> Issue Type: Improvement
> Components: runner-py-interactive

> Assignee: Ning Kang
> Priority: Major
> Time Spent: 6h 40m
> Remaining Estimate: 0h

> With work in https://issues.apache.org/jira/browse/BEAM-7760, Beam pipeline
> converted to DOT then rendered should mark user defined variables on edges.
> With work in https://issues.apache.org/jira/browse/BEAM-7926, it might be
> redundant or confusing to render arbitrary random sample PCollection data on
> edges.
> We'll also make sure edges in the graph corresponds to output -> input
> relationship in the user defined pipeline. Each edge is one output. If
> multiple down stream inputs take the same output, it should be rendered as
> one edge diverging into two instead of two edges.
> For advanced interactivity highlight where each execution highlights the part
> of the pipeline really executed from the original pipeline, we'll also
> provide the support in beta.
