Tom Augspurger commented on ARROW-2667:
---------------------------------------
Note that pandas' `take` is a bit complicated by trying to satisfy two APIs
simultaneously.
There's the NumPy-style take from
[https://docs.scipy.org/doc/numpy/reference/generated/numpy.take.html,] where
negative indices mean slices from the end.
And then there's the "pandas" style `take` where `-1` means "indicator for
missing values, which should be filled with the `na_value` parameter." Other
negative numbers are not allowed.
I'm not sure which is more appropriate for Arrow, but wanted to share a bit of
background.
> [C++/Python] Add pandas-like take method to Array/Column/ChunkedArray
> ---------------------------------------------------------------------

> Key: ARROW-2667
> URL: https://issues.apache.org/jira/browse/ARROW-2667
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, Python
> Reporter: Uwe L. Korn
> Priority: Major
>
> We should add a {{take}} method to {{Array/ChunkedArray/Column}} that takes a
> list of indices and returns a reordered array.
> For reference, see Pandas' interface:
