-------------------------------
Summary: [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
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].
