I'd like to check with you, since you can not create Decimal/Varchar data type column through Impala. Is there any other way to do it? Appreciate if you share some detailed approaches.
Furthermore, if my application is designed to use Impala as query interface with Kudu, is there any work around to create columns for similar precision and data type?
May be the Decimal and Varchar types are not supported in KUDU but you can use INT,FLOAT,DOUBLE and STRING to store any kind of data like alternatives of (Decimal/Varchar).
