Rok Mihevc commented on ARROW-12615:
------------------------------------
ARROW-12499 is about adding ScalarAggregateOptions to Any and All kernels.
[~apitrou] I suppose we need this to match expected behaviour in
[R|https://stat.ethz.ch/R-manual/R-devel/library/stats/html/sd.html] - na.rm
and
[pandas|https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.std.html]
- skip_na.
> [C++] Add options for handling NAs to stddev and variance
