Hi,
what is the best way to do some operation combining two PCollectionView
instances that's not involving any PCollection processing? So far I've been
running it on some fake PCollection of single element and passing the views as
sideinputs:
pipeline.apply(Create.of(fake_element)).apply(ParDo.of(...).withSideInputs(view1,
view2)))...
but the need for fake pcollection is bit awkward so wondering if it can be
avoided?
I can see in beam v2.0.0 there is PCollectionView.getPCollection() so I could
theoretically use one of the views using main input and the other as
sideinput... but the .getPCollection() is annotated as internal so I guess
that's not to be used.
thanks,antony.
