Subject [jira] Created: (OPENJPA-994) Improve performance in M2M findBy operations
Date Fri, 20 Mar 2009 14:12:50 GMT
Improve performance in M2M findBy operations
--------------------------------------------

                 Key: OPENJPA-994
                 URL: https://issues.apache.org/jira/browse/OPENJPA-994
             Project: OpenJPA
          Issue Type: Improvement
            Reporter: Michael Dick


This issue was reported on the users mailing list by Shubbis who noticed reduced performance
with OpenJPA when using M2M relationships. 

Further investigation makes it appear to be a scaling issue, for small numbers of queries
OpenJPA may perform fine, but when the number increases (ie > 50) we start lagging behind.
