> 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.
