Struct mz_dataflow_types::plan::reduce::MonotonicPlan
source · [−]pub struct MonotonicPlan {
pub aggr_funcs: Vec<AggregateFunc>,
pub skips: Vec<usize>,
}
Expand description
Plan for computing a set of hierarchical aggregations with a monotonic input.
Here, the aggregations will be rendered in place. We don’t need to worry about retractions because the inputs are append only, so we can change our computation to only retain the “best” value in the diff field, instead of holding onto all values.
Fields
aggr_funcs: Vec<AggregateFunc>
All of the aggregations we were asked to compute.
skips: Vec<usize>
Set of “skips” or calls to nth()
an iterator needs to do over
the input to extract the relevant datums.
