[jira] [Created] (CALCITE-784) LoggicalAggregate's create method discard any collation traits from input

Milinda Lakmal Pathirage created CALCITE-784:
------------------------------------------------

             Summary: LoggicalAggregate's create method discard any collation traits from input
                 Key: CALCITE-784
                 URL: https://issues.apache.org/jira/browse/CALCITE-784
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Milinda Lakmal Pathirage
            Assignee: Julian Hyde


LogicalAggregate's create method gets the trait set of Convention.NONE from input's cluster, but doesn't use any trait information from the input. But to have proper collation trait set we need to consider input's collation trait set when inferring LogicalAggregate's traits.
