Review comment:
Yes, that is meant for number 1) in
https://github.com/apache/arrow/pull/11724#discussion_r751195257 right? My
question is regarding unknown column name, that is number 2) =)
If for example we have a table with columns `a` and `b` and you specify the
encoding for unknown column `c` - it does nothing and I am not sure how to
raise an error in this case.
That is if I understood number 2) correctly.
