----------------------------------

             Summary: Serialize and Deserialize Table objects
                 Key: ARROW-2658
                 URL: https://issues.apache.org/jira/browse/ARROW-2658
             Project: Apache Arrow
          Issue Type: New Feature
            Reporter: Kunal Gosar


Add support for serializing and deserializing pyarrow Tables. This would allow using Table objects in plasma and DataFrames can be converted to a Table object as intermediary for serialization. Currently I see the following when trying this operation:
{code:java}
In [36]: pa.serialize(t)

SerializationCallbackError                Traceback (most recent call last)

SerializationCallbackError: pyarrow does not know how to serialize objects of type <class 'pyarrow.lib.Table'>.
