> Implement Native Vector GroupBy using fast hash table technology developed
> for Native Vector MapJoin, etc.
> Patch is currently limited to a single Long key with a single COUNT
> aggregation. Or, a single Long key and no aggregation also known as
> duplicate reduction.
> 3 new classes introduces that stored the count in the slot table and don't
> allocate hash elements:
> {noformat}
> COUNT(column) VectorGroupByHashLongKeyCountColumnOperator
> COUNT(key) VectorGroupByHashLongKeyCountKeyOperator
> COUNT(*) VectorGroupByHashLongKeyCountStarOperator
> {noformat}
> And the duplicate reduction operator a single Long key:
> {noformat}
> VectorGroupByHashLongKeyDuplicateReductionOperator
> {noformat}
