-----------------------------------
Summary: create a CLI to convert a pipeline to graphviz dot format
Key: BEAM-7677
URL: https://issues.apache.org/jira/browse/BEAM-7677
Project: Beam
Issue Type: Improvement
Components: beam-model
Reporter: Chad Dombrova
As a Beam developer (especially one using python or go) I want a way to convert
a pipeline to graphviz dot format so that I can easily visualize it.
The Beam source comes with a great utility in the form of
[PortablePipelineDotRenderer.java|https://github.com/apache/beam/blob/2df702a1448fa6cbd22cd225bf16e9ffc4c82595/runners/core-construction-java/src/main/java/org/apache/beam/runners/core/construction/renderer/PortablePipelineDotRenderer.java#L29].
It seems like a great util to wrap with a CLI, so that it can be easily
accessed from other languages and just for general ease-of-use for java
developers.
The tool would take an input pipeline message as either a path to a file or via
stdin, and would output a dot string to stdout or to a file.
I'm happy to make a PR for this, but I noticed there's not any existing CLI
tools included with Beam, so I would need some guidance on where to put the
source code, and where to build the bin tool.
thanks!
