Module mz_transform::reduce_reduction
source · Expand description
Breaks complex Reduce variants into a join of simpler variants.
Specifically, any Reduce that contains two different “types” of aggregation,
in the sense of ReductionType, will be broken in to one Reduce for each
type of aggregation, each containing the aggregations of that type,
and the results are then joined back together.
