Subject [jira] Created: (DERBY-573) Provider support for optimizer overrides in Derby.
Date Fri, 16 Sep 2005 03:40:54 GMT
Provider support for optimizer overrides in Derby.

         Key: DERBY-573
         URL: http://issues.apache.org/jira/browse/DERBY-573
     Project: Derby
        Type: New Feature
  Components: SQL  
    Reporter: Mamta A. Satoor
 Assigned to: Mamta A. Satoor 

Derby's query optimizer usually makes the best choice of join order and access path. The default
join strategy ususally works the best too. However, there are some cases in which user may
want to override the optimizer or the default values. Providing support for optimizer overrides
will allow users to hand-tune the optimizer for queries.
