             Summary: Support dynamic schema in Table Function
                 Key: FLINK-6196
                 URL: https://issues.apache.org/jira/browse/FLINK-6196
             Project: Flink
          Issue Type: Improvement
            Reporter: Zhuoluo Yang
            Assignee: Zhuoluo Yang


In many of our use cases. We have to decide the schema of a UDTF at the run time. For example. udtf('c1, c2, c3') will generate three columns for a lateral view.
Most systems such as calcite and hive support this feature. However, the current implementation of flink didn't implement the feature correctly.
