----------------------------------------
I think ARROW-9054 covers this; can you confirm?
> [C++][Compute] Optionally ignore NaN in sum kernel
> --------------------------------------------------
>
> Key: ARROW-9687
> URL: https://issues.apache.org/jira/browse/ARROW-9687
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Yibo Cai
> Priority: Major
>
> For floating types, sum kernel returns NaN if there's at least one NaN in the
> input array.
> It's useful to provide an option to ignore NaN(treat as 0) in summing,
> similar to
> [numpy.nansum|https://numpy.org/doc/stable/reference/generated/numpy.nansum.html].
