---------------------------------------
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.
