> Key: ARROW-13389
> URL: https://issues.apache.org/jira/browse/ARROW-13389
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Ian Cook
> Priority: Minor
>
> Currently the {{coalesce}} kernel treats {{NaN}} as a non-null value.
> Consider adding a boolean option to this kernel that could be used to make it
> treat {{NaN}} values the same as null values. This would allow the code added
> in ARROW-13201 to be much simplified.
