[jira] [Created] (ARROW-2451) Handle more dtypes efficiently in custom numpy array serializer.

Robert Nishihara created ARROW-2451:
---------------------------------------

             Summary: Handle more dtypes efficiently in custom numpy array serializer.
                 Key: ARROW-2451
                 URL: https://issues.apache.org/jira/browse/ARROW-2451
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Robert Nishihara


Right now certain dtypes like bool or fixed length strings are serialized as lists, which is inefficient. We can handle these more efficiently by casting them to uint8 and saving the original dtype as additional data.
