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)
