Enum dataflow_types::plan::reduce::HierarchicalPlan

pub enum HierarchicalPlan {
    Monotonic(MonotonicPlan),
    Bucketed(BucketedPlan),
}

Plan for computing a set of hierarchical aggregations.

In the append-only setting we can render them in-place with monotonic plans, but otherwise, we need to render them with a reduction tree that splits the inputs into small, and then progressively larger, buckets

Variants

Monotonic(MonotonicPlan)

Tuple Fields

0: MonotonicPlan

Plan hierarchical aggregations under monotonic inputs.

Bucketed(BucketedPlan)

Tuple Fields

0: BucketedPlan

Plan for hierarchical aggregations under non-monotonic inputs.
