> Add Codegen support to array higher-order-functions
> ---------------------------------------------------
>
> Key: SPARK-37019
> URL: https://issues.apache.org/jira/browse/SPARK-37019
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Adam Binford
> Priority: Major
>
> Currently all of the higher order functions use CodegenFallback. We can
> improve the performance of these by adding proper codegen support, so the
> function as well as all children can be codegen'd, and it can participate in
> WholeStageCodegen.
> This ticket is for adding support to array-based higher-order functions.
