Hey - yeah definitely a real concern as it needs driver heap to scale with
the size of the metadata of the table you are going to read in.
We could be creative to add heuristics around reading the metadata at all
if it is too large or add the ability to spill the existing metadata to disk.
Do you have any preferences/thoughts?
