> -------------------------------------------
>
> Key: ARROW-13849
> URL: https://issues.apache.org/jira/browse/ARROW-13849
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Neal Richardson
> Assignee: David Li
> Priority: Major
> Labels: kernel
> Fix For: 6.0.0
>
>
> We have min_max but that returns a struct array. At some point we will want
> compute kernels that we can call in a ProjectNode that will allow us to get
> at struct array elements, but for now it would be nice to have (hash_)min and
> max that just give the scalar we want.
