Wes McKinney commented on ARROW-488:
------------------------------------
As currently scoped, yes. This functionality is not available in
{{arrow::compute::Cast}} though, so perhaps we can repurpose this JIRA to add
this functionality, which may be a bit more complicated (since {{Cast}} is not
yet able to deal with any null sentinels at all)
> [Python] Implement conversion between integer coded as floating points with
> NaN to an Arrow integer type
