Enum KernelBackend 

pub enum KernelBackend {
    Auto,
    ArrowRust,
    Python,
}

Kernel backend preference for lowerable batch/scalar nodes.

Backend selection is implemented by the M14 kernel rungs. In A1 this is a validated, report-visible planner input only.

Variants

Auto

Let the planner choose the backend for a lowerable node.

ArrowRust

Use Datum’s Rust/Arrow backend.

Python

Use a Python/C++ Arrow backend when that backend is available and selected.
