Antoine Pitrou created ARROW-2660: ------------------------------------- Summary: [Python] Experiment with zero-copy pickling Key: ARROW-2660 URL: https://issues.apache.org/jira/browse/ARROW-2660 Project: Apache Arrow Issue Type: Wish Components: Python Affects Versions: 0.9.0 Reporter: Antoine Pitrou
PEP 574 has an implementation ready and a PyPI-available backport (at [https://pypi.org/project/pickle5/] ). Adding experimental support for it would allow for zero-copy pickling of Arrow arrays, columns, etc. I think it mainly involves implementing {{reduce_ex}} on the {{Buffer}} class, as described in [https://www.python.org/dev/peps/pep-0574/#producer-api] In addition, the consumer API added by PEP 574 could be used in Arrow's serialization array, to avoid or minimize copies when serializing foreign objects. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
