>
> Key: SPARK-33091
> URL: https://issues.apache.org/jira/browse/SPARK-33091
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.1, 3.1.0
> Reporter: Hyukjin Kwon
> Priority: Major
>
> This is a kind of a followup of SPARK-32646. New JIRA was filed to control

> this, we should better use {{foreach}}.
