> Improve ArrayInsert if the position is foldable and equals to zero.
> -------------------------------------------------------------------
>
> Key: SPARK-43137
> URL: https://issues.apache.org/jira/browse/SPARK-43137
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.5.0
> Reporter: jiaan.geng
> Priority: Major
>
> We want make array_prepend reuse the implementation of array_insert, but it
> seems a bit performance worse if the position is foldable and equals to zero.
> The reason is that always do the check for position is negative or positive,
> and the code is too long. Too long code will lead to JIT failed.
