Antoine Pitrou updated ARROW-2660: ---------------------------------- Description: 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 layer, to avoid or minimize copies when serializing foreign objects. was: PEP 574 has an implementation ready and a PyPI-available backport (at [https://pypi.org/project/pickle5/] ).
