---------------------------------
Hi Will,
I posted the issue there as well because I'm not sure what the root cause is
and where it belongs to as the issue occurred while using the
`write_to_dataset` method of pyarrow. Thank for linking them together. By the
way, what a small world, I hope you're doing well!
