sgilmore10 opened a new issue, #38422:
URL: https://github.com/apache/arrow/issues/38422
### Describe the enhancement requested
It would be nice if there was a `NumNulls` property on the
`arrow.array.Array` base class. Currently, the only way to figure out the
number of nulls is count the number of `false` values in the `Valid` array:
```matlab
>> a = arrow.array([1 2 NaN 4 5 6 NaN 8 9 10 NaN]);
>> invalidValues = ~a.Valid;
>> numNulls = nnz(invalidValues)
numNulls =
3
```
It would be nice if `NumNulls` was already a property on the array class. As
@kou mentioned, we can use the `arrow::Array::null_count()` to get the number
of nulls.
