Subject [jira] [Created] (ARROW-86) Implement zero-copy Arrow-to-Pandas conversion
Date Mon, 28 Mar 2016 15:59:25 GMT
Uwe L. Korn created ARROW-86:

             Summary: Implement zero-copy Arrow-to-Pandas conversion
                 Key: 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
 * 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.
