Wes McKinney updated ARROW-823:
-------------------------------
Fix Version/s: (was: 0.14.0)
0.15.0
> [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
> Priority: Major
> Fix For: 0.15.0
>
>
> 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.
