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