with Large Files
URL: https://github.com/apache/drill/pull/1978#issuecomment-585138433
I don't think that it is a good idea to add format config to ignore a
specific column for star queries. If the user wants to see specific columns, he
should specify them in the query.
By the way, if data is too large, is it possible to read it by batches?
