Personally, I don't use "." in my code. But parquet might used to store metadata. Imagine: 1. a mysql or data analysis system uses "tablename.information_schema" or something else as column ( this is commonly used, right?) 2. a system might use special character to store "internal column" ( or hidden column ) So I don't think "." can be regard as unexists. Maybe we can: 1. Uses column path 2. Says this only works on root columns, leafs are not included. -- This is an automated message from the Apache Git Service.
