Apache Spark reassigned SPARK-35384:
------------------------------------
Assignee: Apache Spark
> 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
> Assignee: Apache Spark
> 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.
