[jira] [Updated] (ARROW-5931) [C++] Extend extension types facility
to provide for serialization and deserialization in IPC roundtrips
[ https://issues.apache.org/jira/browse/ARROW-5931?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wes McKinney updated ARROW-5931:
--------------------------------
Description:
A use case here is when an array needs to reference some external data. For example, suppose that we wanted to implement an array that references a sequence of Python objects as {{PyObject*}}. Obviously, a {{PyObject*}} must be managed by the Python interpreter.
For a vector of some {{T*}} to be sent through the IPC machinery, it must be embedded in some Arrow type on the wire. For example, the memory resident version of {{PyObject*}} might be 8-bytes per value (1 pointer per value) while being serialized to the binary IPC protocol, such {{PyObject*}} values must be serialized into an Arrow Binary type.
