> Python: Pandas zero-copy for ListArrays conversion
> --------------------------------------------------
>
> Key: ARROW-489
> URL: https://issues.apache.org/jira/browse/ARROW-489
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Uwe Korn
> Priority: Major
>
> In the case of the conversion of a list column to a pandas column, currently
> we always do a copy even though in the numeric case, we could avoid it most
> of the time. To enable zero-copy conversions, we need to pass a Python
> reference to a {{pyarrow.Column}} to the {{ConvertColumnToPandas}} inside of
> {{ConvertListsLike}}.
