In principle we could aggregate the partials via a `ListArray<i32, PrimitiveArray<T>>`, and merge them by concatenating the results on a single `PrimitiveArray<T>` per group (and then compute the aggregate that requires all results in the `finish`). But I agree that the majority of cases we want an online estimate. -- This is an automated message from the Apache Git Service.
