slim bouguerra created CALCITE-1758:
---------------------------------------

             Summary: Push down to druid the order by limit operator
                 Key: CALCITE-1758
                 URL: https://issues.apache.org/jira/browse/CALCITE-1758
             Project: Calcite
          Issue Type: Improvement
          Components: druid
            Reporter: slim bouguerra
            Assignee: Julian Hyde
             Fix For: 1.13.0


Push as much as we can order by limit operators.
This use to be not possible because of the way druid bucket the data. 
With Extraction dimension specs we can now set granularity to all and craft the extraction dimension spec in order to make time as new group by column.
