Subject [jira] Created: (HIVE-704) join order should be based on table sizes
Date Wed, 29 Jul 2009 05:44:14 GMT
join order should be based on table sizes
-----------------------------------------

                 Key: HIVE-704
                 URL: https://issues.apache.org/jira/browse/HIVE-704
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Namit Jain


Currently, hive uses the same order as specified by the user in the query.

It would be great if that order can be based on the size of tables - largest table should
be outermost table.
