kennknowles opened a new issue, #19218:
URL: https://github.com/apache/beam/issues/19218
Users often ask how they can reason about the pipeline translation. The
Flink UI display a confusingly large graph without any trace of the original
Beam pipeline:
WordCount:
!wordcount.png!
TFX:
!tfx.png!
Some aspects which make understanding these graphs hard:
* Users don't know how the Runner maps Beam to Flink concepts
* The UI is awfully slow / hangs when the pipeline is reasonable complex
* The operator names seem to use `transform.getUniqueName()` which doesn't
generate readable name
* So called Chaining combines operators into a single operator which makes
understanding which Beam concept belongs to which Flink concept even harder
