Subject [jira] [Created] (FLINK-6963) User Defined Operator
Date Wed, 21 Jun 2017 09:29:00 GMT
Shaoxuan Wang created FLINK-6963:
------------------------------------

             Summary: User Defined Operator
                 Key: FLINK-6963
                 URL: https://issues.apache.org/jira/browse/FLINK-6963
             Project: Flink
          Issue Type: New Feature
          Components: Table API & SQL
            Reporter: Shaoxuan Wang
            Assignee: Jark Wu
             Fix For: 1.4.0


We are proposing to add an User Defined Operator (UDOP) interface. As oppose to UDF(scalars
to scalar)/UDTF(scalar to table)/UDAGG(table to scalar), this UDOP allows user to describe
a business logic for a table to table conversion.
