[jira] [Commented] (FLINK-17855) UDF with parameter Array(Row) can not work

["Jark Wu (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-17855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17112751#comment-17112751 ] 

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?
