-------------------------------------
Summary: [Serialization] Support OrderedDict properly
Key: ARROW-1625
URL: https://issues.apache.org/jira/browse/ARROW-1625
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Philipp Moritz
At the moment what happens when we serialize an OrderedDict and then
deserialize it, it will become a normal dict! This can be reproduced with
{code}
import pyarrow
import collections
d = collections.OrderedDict([("hello", 1), ("world", 2)])
type(pyarrow.serialize(d).deserialize))
{code}
which will return "dict". See also
