> [C++][Python] Unregister compute functions
> ------------------------------------------
>
> Key: ARROW-16211
> URL: https://issues.apache.org/jira/browse/ARROW-16211
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: C++, Python
> Reporter: Vibhatha Lakmal Abeykoon
> Priority: Major
>
> In general, when using UDFs, the user defines a function expecting a
> particular outcome. When building the program, there needs to be a way to
> update existing function kernels if it expands beyond what is planned before.
> In such situations, there should be a way to remove the existing definition
> and add a new definition. To enable this, the unregister functionality has to
> be included.
