--------------------------------
Summary: Improve performance for ApplyFunctionExpression
Key: SPARK-35361
URL: https://issues.apache.org/jira/browse/SPARK-35361
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.2.0
Reporter: Chao Sun
When the `ScalarFunction` itself is trivial, `ApplyFunctionExpression` could
incur significant runtime cost with `zipWithIndex` call. This proposes to move
the call outside the loop over each input row.
