             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`.
