WeiZhong94 commented on issue #9865: [FLINK-14212][python] Support no-argument Python UDFs. URL: https://github.com/apache/flink/pull/9865#issuecomment-541303687 > > @JingsongLi I noticed that the "getScalarFunction" method in "ScalarSqlFunction" of blink planner was replaced by "makeFunction" method. I think using "getScalarFunction" to get the initial ScalarFunction object and check its language type makes more sense here so I re-add the method. Please take a look at this PR to make sure it does not cause any side effects to blink planner :). > > LGTM, it is reasonable, can you just use scala val to scalarFunction just like `TableSqlFunction`? Thanks for your reply! That makes sense to me. I have updated the code in the latest commit.
