Wes McKinney commented on ARROW-3686:
-------------------------------------
We have a {{mask}} argument to {{pyarrow.array}} already. It would seem
reasonable to detect {{ma.MaskedArray}} and grab its mask
> [Python] Support for masked arrays in to/from numpy
> ---------------------------------------------------
>
> Key: ARROW-3686
> URL: https://issues.apache.org/jira/browse/ARROW-3686
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 0.11.1
> Reporter: Maarten Breddels
> Priority: Major
> Fix For: 0.13.0
>
>
> Again, in this PR for vaex:
> [https://github.com/maartenbreddels/vaex/pull/116] I support masked arrays,
> it would be nice if this goes into pyarrow. If this approach looks good I
> could do a PR.
