- GroupByShape
- MergedAggregate
- Reads the column $aggregate->outputName() as partials and merges them; its output is $aggregate's value(), so wave 2 of a shuffle and the parent's finisher reuse the group-by processor unchanged.
- PartialAggregate
- Aggregates like $aggregate; its output column holds partial(), so wave 1 of a shuffle reuses the group-by processor unchanged.
