Philipp Moritz created ARROW-1924:
-------------------------------------
Summary: [Python] Bring back pickle=True option for serialization
Key: ARROW-1924
URL: https://issues.apache.org/jira/browse/ARROW-1924
Project: Apache Arrow
Issue Type: Bug
Reporter: Philipp Moritz
We need to revert https://issues.apache.org/jira/browse/ARROW-1758
The reason is that the semantics for pickle=True is slightly different from
just using (cloud-)pickle as the custom serializer:
If pickle=True is used, the object can be deserialized in any process, even if
a deserializer for that type_id has not been registered in that process. On the
other hand, if (cloud-)pickle is used as a custom serializer, the object can
only be deserialized if pyarrow has the type_id registered and can call the
deserializer.
