[jira] [Created] (KYLIN-2011) Query without order by should not leverage topn measure

hongbin ma created KYLIN-2011:
---------------------------------

             Summary: Query without order by should not leverage topn measure
                 Key: KYLIN-2011
                 URL: https://issues.apache.org/jira/browse/KYLIN-2011
             Project: Kylin
          Issue Type: Bug
            Reporter: hongbin ma
            Assignee: hongbin ma
            Priority: Minor


sql_topn/query45.sql:


select seller_id, sum(price) as s from test_kylin_fact
  where lstg_format_name='FP-GTC' 
  group by seller_id


this query does not have order by, however it will still leverage topn measure. Since topn use double encoding instead of decimal encoding, there's precision  loss.
