Subject [jira] Updated: (OPENJPA-1592) PCData generation has performance issues
Date Mon, 22 Mar 2010 16:59:27 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-1592?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kevin Sutter updated OPENJPA-1592:
----------------------------------

          Description: 
>From the parent task...

Looking to improve the efficiency of the DataCache and QueryCache. Benchmarking is showing
that the constant conversion from the POJO format to and from the PCData format is taking
its toll. After talking with Patrick on the subject, he pointed out the PCDataGenerator which
enhances the Entities for use in the Cache (vs using whole new PCData objects). The use of
the PCDataGenerator is configured via the openjpa.DynamicDataStructs property. 


    Affects Version/s: 2.0.0
                       2.0.0-beta2
