Mamta A. Satoor commented on DERBY-573: --------------------------------------- I can look into modifying the RunTimeStatistics to indicate that user overrides are being used. Also, I will see how parser can be modified to look for --DERBY-HINTS rather than just --PROPERTIES. If people prefer DERBY-PROPERTIES over DERBY-HINTS, please put comment stating so to this JIRA entry. > 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 > Versions: 10.2.0.0 > Reporter: Mamta A. Satoor > Assignee: Mamta A. Satoor > Attachments: optimizeroverrides.html > > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
