> Python: Implement zero-copy Arrow-to-Pandas conversion
> ------------------------------------------------------
>
> Key: ARROW-86
> URL: https://issues.apache.org/jira/browse/ARROW-86
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Uwe Korn
> Assignee: Uwe Korn
> Priority: Major
> Fix For: 0.1.0
>
>
> For this to work, we need:
> * a check if the Arrow Array could be represented as Pandas Series using the
> same memory buffer
> * a {{numpy.ndarray}} subclass that keeps a reference to the Arrow Array
> With the NumPy C-API it is already possible to create a {{numpy.ndarray}}
> instance that uses the Arrow Array memory buffer internally but there is no
> way to keep track if the {{numpy.ndarray}} still lives or the underlying
> memory can be free'd.
