描述

Description

This is the default backend in nutpie and could possibly also be the one in PyMC.

@aseyboldt suggests it may be much more performant than our numpy default backend atm.

研究方向
This feature request proposes adding a PyArrow backend for PyMC, referencing nutpie's existing implementation. To proceed, a contributor should study PyMC's current numpy backend (e.g., pymc/sampling/backends/) and understand the interface. Reviewing nutpie's PyArrow backend code would provide a reference implementation. Engaging with the issue author or maintainers (e.g., @aseyboldt) for more detailed requirements is recommended. The scope of work includes performance benchmarking and ensuring compatibility with PyMC's sampling methods.
