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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
