------------------------------------
Summary: Add to_numpy functions
Key: ARROW-2295
URL: https://issues.apache.org/jira/browse/ARROW-2295
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Lawrence Chan
There are `to_pandas()` functions, but no `to_numpy()` functions. I'd like to
propose that we include both.
Also, `pyarrow.lib.Array.to_pandas()` returns a `numpy.ndarray`, which imho is
very confusing :). I think it would be more intuitive for the `to_pandas()`
functions to return `pandas.Series` and `pandas.DataFrame` objects, and the
`to_numpy()` functions to return `numpy.ndarray` and either a dict of
`numpy.ndarray` or a structured `numpy.ndarray` depending on a flag, for
example. The `to_pandas()` function is of course welcome to use the
`to_numpy()` func to avoid the additional indexes and whatnot of the
`pandas.Series`.
