[jira] [Created] (ARROW-2249) [Java/Python] in-process vector sharing from Java to Python

Uwe L. Korn created ARROW-2249:
----------------------------------

             Summary: [Java/Python] in-process vector sharing from Java to Python
                 Key: ARROW-2249
                 URL: https://issues.apache.org/jira/browse/ARROW-2249
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Java - Vectors, Python
            Reporter: Uwe L. Korn
            Assignee: Uwe L. Korn
             Fix For: 0.10.0


Currently we seem to use in all applications of Arrow the IPC capabilities to move data between a Java process and a Python process. While this is 0-serialization, it is not zero-copy. I'm going to have a first shot at exposing Java Vectors in Python as {{pyarrow.Array}}.

This issue can also be used as a tracker for the various sub-tasks that will need to be done to complete this rather large milestone.
