Philipp Moritz commented on ARROW-17719:
----------------------------------------
I noticed the mechanism was introduced in
https://issues.apache.org/jira/browse/ARROW-8058 – do you have thoughts on this
[~fsaintjacques] or [~bkietz] ?
The mechanism itself can be useful, but I'm suggesting to set a different
default.

> There is a good bug report about this in

> a parquet partition are null. We should either handle this case better or
> give a better error message.
