Jark Wu commented on FLINK-17855:
---------------------------------
I think this is reasonable, because planner can't infer what's the exact type
of Row. Users should use type hints or override {{getTypeInference}} to tell
planner the parameter information.
Do you mean want to support {{Row[]}} parameter without type hints or
{{getTypeInference}} implementation?
> UDF with parameter Array(Row) can not work
