-------------------------------------

             Summary: Push order/limit to Druid historical when approximate results are allowed

                 Key: HIVE-18732
                 URL: https://issues.apache.org/jira/browse/HIVE-18732
             Project: Hive
          Issue Type: Improvement
            Reporter: slim bouguerra


Druid 0.11 allow force push down of Order by Limit to historicals using a context Query Flag
\{code} forcePushDownLimit\{code}. [http://druid.io/docs/latest/querying/groupbyquery.html]

As per the docs [http://druid.io/docs/latest/querying/groupbyquery.html|http://druid.io/docs/latest/querying/groupbyquery.html.],
this is a great optimization that can be used if the approximate results are allowed.
