Subject [jira] [Created] (HIVE-3562) Some limit can be pushed down to map stage
Date Wed, 10 Oct 2012 05:13:05 GMT
Navis created HIVE-3562:

             Summary: Some limit can be pushed down to map stage
                 Key: HIVE-3562
             Project: Hive
          Issue Type: Bug
            Reporter: Navis
            Assignee: Navis
            Priority: Trivial

Queries with limit clause (with reasonable number), for example
select * from src order by key limit 10;

makes operator tree, 

But LIMIT can be partially calculated in RS, reducing size of shuffling.
