Ryan Blue commented on PARQUET-41:
----------------------------------
Great, thanks [~Ferd]! Could you also tell us a bit more about how this works
and the approach you're taking? At first glance, we need quite a bit more in
the format to specify exactly what the structure means and how to use it. It
would be good to discuss that here, too.
