@saulshanabrook I've pushed my latest work (rebased off the latest master).
I'm not sure it's quite complete, but feel free to review and comment. FYI, the
one piece of code that's given me the most trouble is the `SelectedField`
extractor. It's passing all of the test cases I've thrown at it, but I can't
quite convince myself that it's complete/correct. If you have some ideas for
how to simplify it to make it easier to understand I welcome them.
If you'd like to submit actual changes to the code in this PR, please
submit a PR against our
https://github.com/VideoAmp/spark-public/tree/spark-4502-parquet_column_pruning
branch, and I will review it there.
Thanks for your help.
