Uwe L. Korn created ARROW-86:
--------------------------------
Summary: 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 L. Korn
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.
