public class DruidUserDefinedTableMacro extends SchemaAwareUserDefinedTableMacro implements AuthorizableOperator
Base class for input-source-specific table functions with arguments derived from a catalog external table definition. Such functions work in conjunction with the EXTEND key word to provide a schema. Example of the HTTP form: 
 INSERT INTO myTable SELECT ...
 FROM TABLE(http(
     userName => 'bob',
     password => 'secret',
     uris => ARRAY['http:foo.com/bar.csv'],
     format => 'csv'))
   EXTEND (x VARCHAR, y VARCHAR, z BIGINT)
 PARTITIONED BY ...
