Expand description
Plan for computing a set of accumulable aggregations.
We fuse all of the accumulable aggregations together and compute them with one dataflow fragment. We need to be careful to separate out the aggregations that apply only to the distinct set of values. We need to apply a distinct operator to those before we combine them with everything else.
Fields
full_aggrs: Vec<AggregateExpr>
All of the aggregations we were asked to compute, stored in order.
simple_aggrs: Vec<(usize, usize, AggregateExpr)>
All of the non-distinct accumulable aggregates. Each element represents: (index of the aggregation among accumulable aggregations, index of the datum among inputs, aggregation expr) These will all be rendered together in one dataflow fragment.
distinct_aggrs: Vec<(usize, usize, AggregateExpr)>
Same as above but for all of the DISTINCT
accumulable aggregations.
