> 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.
