Ismaël Mejía commented on BEAM-6747:
------------------------------------
Java pipelines are written depending mostly in the core SDK. What is not clear
for me is how can I use an external transform if the way to do it is not
exposed in the SDK. Or is it exposed somehow and I just did not understand how
to get it done? As a simple case, imagine that I want to execute a transform, a
simple 'ParDo' like one written in python as a middle step from Java, can you
share a snippet of how can I achieve this?
Dependencies on runners should be mostly for runtime behavior, otherwise the
whole Beam portability premise would be broken.
