> [C++] Expand Python-UDF support to Arrow Substrait
> --------------------------------------------------

> Key: ARROW-16968
> URL: https://issues.apache.org/jira/browse/ARROW-16968
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Yaron Gvili
> Assignee: Yaron Gvili
> Priority: Major
>
> Currently, Python-UDFs are supported in Arrow at a low-level of abstraction.
> This issue is about expanding this support to Arrow Substrait, which is at a
> higher-level. This is intended for the Py/Arrow support of the use case in
> which a Substrait plan with Python UDFs is manually expressed using Ibis,
> automatically represented using Substrait, and automatically executed using
> Py/Arrow.
