   I would anticipate this working in much the same way as it currently does with the [`Accumulator`](https://docs.rs/datafusion/latest/datafusion/physical_plan/trait.Accumulator.html) interface which is also stateful. The only difference would be using `ScalarValue` instead of `ArrayRef`. Am I missing something here as to why we would need to do something different?
