Chao Sun updated SPARK-35384:

> Improve performance for InvokeLike.invoke
> -----------------------------------------
>
>                 Key: SPARK-35384
>                 URL: https://issues.apache.org/jira/browse/SPARK-35384
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.2.0
>            Reporter: Chao Sun
>            Priority: Minor
>
> `InvokeLike.invoke` uses `map` to evaluate arguments:
> {code:java}
> val args = arguments.map(e => e.eval(input).asInstanceOf[Object])
> if (needNullCheck && args.exists(_ == null)) {
>   // return null if one of arguments is null
>   null
> } else { 
> {code}
> which seems pretty expensive if the method itself is trivial. We can change it to a plain for-loop.
