Expand description
Plan for collating the results of computing multiple aggregation types.
TODO: could we express this as a delta join
Fields
accumulable: Option<AccumulablePlan>
Accumulable aggregation results to collate, if any.
hierarchical: Option<HierarchicalPlan>
Hierarchical aggregation results to collate, if any.
basic: Option<BasicPlan>
Basic aggregation results to collate, if any.
aggregate_types: Vec<ReductionType>
When we get results back from each of the different aggregation types, they will be subsequences of the sequence aggregations in the original reduce expression. We keep a map from output position -> reduction type to easily merge results back into the requested order.
