> Based on create function and table.we can register a udf,udaf,udtf use sql:
> {code}
> CREATE FUNCTION [IF NOT EXISTS] [catalog_name.db_name.]function_name AS class_name;
> DROP FUNCTION [IF EXISTS] [catalog_name.db_name.]function_name;
> ALTER FUNCTION [IF EXISTS] [catalog_name.db_name.]function_name RENAME TO new_name;
> {code}
> {code}
> CREATE function 'TOPK' AS 'com.xxxx.aggregate.udaf.distinctUdaf.topk.ITopKUDAF';
> INSERT INTO db_sink SELECT id, TOPK(price, 5, 'DESC') FROM kafka_source GROUP BY id;
