> Aggregate elimination with UNIQUE and NOT NULL column

> Key: HIVE-17041

> Project: Hive
> Issue Type: Sub-task

> Affects Versions: 3.0.0

>
> If columns are part of a GROUP BY expression and they are UNIQUE and do not
> accept NULL values, i.e. PK or UK+NOTNULL, the _Aggregate_ operator can be
> transformed into a Project operator, as each row will end up in a different
> group.
> For instance, given that _pk_ is the PRIMARY KEY for the table, the GROUP BY
> could be removed from grouping columns for following query:
> {code:sql}
> SELECT pk, value1
> FROM table_1
> GROUP BY value1, pk, value2;
> {code}
