Alex Hagerman updated ARROW-2658:
---------------------------------
Summary: [Python] Serialize and Deserialize Table objects (was: Serialize
and Deserialize Table objects)
> [Python] Serialize and Deserialize Table objects
> ------------------------------------------------
>
> Key: ARROW-2658
> URL: https://issues.apache.org/jira/browse/ARROW-2658
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Reporter: Kunal Gosar
> Priority: Major
>
> 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)
> <ipython-input-36-48cee5dfe30a> in <module>()
> ----> 1 pa.serialize(t)
> ~/dev/arrow/python/pyarrow/serialization.pxi in pyarrow.lib.serialize()
> 336
> 337 with nogil:
> --> 338 check_status(SerializeObject(context, wrapped_value,
> &serialized.data))
