Eron Wright commented on SPARK-7400:
-------------------------------------
I am thinking about ML scenarios here, with the ultimate goal of using a
DataFrame with PortableDataStream-type columns in an ML pipeline. The scenario
is to process image data. Perhaps a transformer would map PortableDataStream
to Vector (decoding and vectorizing each image).
