https://github.com/apache/spark/pull/18945
> Another rough thought for a feasible way I could think to keep the
current behaviour (to be more specific, to match the types with / without Arrow
optimization, IIUC) is, to make a generator wrapper to check if None exists in
the results for columns where the type is int and nullable.
I'm not sure I follow @HyukjinKwon , we can just look at the `pdf` when it
is first created but before any type conversions and just not do anything if it
the column is a nullable int with null values. Is this similar to what you're
suggesting?
