   > I remember back then in Oracle days, there was VARCHAR and VARCHAR2 data types, just thinking aloud if it can be reused like VARCHAR is UTF8 ArrowType, VARCHAR2 is UTF8View
   
   Interesting @comphead , we are currently have the option to disable it and fall back to UTF8:
   set datafusion.sql_parser.map_varchar_to_utf8view = false;
   
   But it seems if we also have the VARCHAR/VARCHAR2 , it's also a improvement from customer side. Thanks!
