In other words, revertĀ, at least in spirit? I agree :-)

We are currently converting the Calcite Rel tree to Beam by recursively building a tree of nested PTransforms. This results in a weird nested graph in the dataflow UI where each node contains its inputs nested inside of it. I'm going to change the internal data structure for converting the tree from a PTransform to a PCollection, which will result in a more accurate representation of the tree structure being built and should simplify the code as well. This will not change the public interface to SQL, which will remain a PTransform. Any thoughts or objections?

I was also wondering if there are tools for visualizing the Beam graph aside from the dataflow runner UI. What other tools exist?
