> Today, aggregates like AVG are output from VectorGroupByOperator as a STRUCT.  This prevents downstream operators in map, reduce shuffle, and reduce from being vectorized.
> Take the STRUCT fields used for AVG (for example) and output them (vector) columns.
> NOTE: downstream VectorGroupByOperator needs to accept column form…
> •	That is, (reduce) merge of partial aggregates is different than map.
