Wes McKinney created ARROW-823:
----------------------------------
Summary: [Python] Devise a means to serialize arrays of arbitrary
Python objects in Arrow IPC messages
Key: ARROW-823
URL: https://issues.apache.org/jira/browse/ARROW-823
Project: Apache Arrow
Issue Type: New Feature
Components: Python
Reporter: Wes McKinney
Practically speaking, this would involve a "custom" logical type that is
"pyobject", represented physically as an array of 64-bit pointers. On
serialization, this would need to be converted to a BinaryArray containing
pickled objects as binary values
At the moment, we don't yet have the machinery to deal with "custom" types
where the in-memory representation is different from the on-wire
representation. This would be a useful use case to work through the design
issues
Interestingly, if done properly, this would enable other Arrow implementations
to manipulate (filter, etc.) serialized Python objects as binary blobs.
