Proposed changes
Many time, our users want to use UDFs they developed to ETL the data when loading the data into Doris.But currently,
broker loaddoes not support to use UDF. As UDF belongs to a database, it needs to check whether it has theSELECTpermission of the database. This patch try to solve this problem.Types of changes
