Subject [jira] Created: (GERONIMO-665) CMP - Prefetching of CMP and CMR fields
Date Tue, 07 Jun 2005 23:38:40 GMT
CMP - Prefetching of CMP and CMR fields
---------------------------------------

         Key: GERONIMO-665
         URL: http://issues.apache.org/jira/browse/GERONIMO-665
     Project: Geronimo
        Type: New Feature
  Components: OpenEJB  
    Versions: 1.0-M4    
    Reporter: Gianny Damour
 Assigned to: Gianny Damour 
    Priority: Minor


The CMP engine needs to be improved to allow for the prefetching of CMP and CMR fields.

When a CMP field needs to be fetched from the underlying database, it should be possible to
specify a group of related CMP and CMR fields to be loaded at the same time (the current implementation
fetches all the CMP fields and we have no mean to control this behavior). Also, when a CMR
field is loaded as part of a group, it should also be possible to specify a group a CMP and
CMR fields defined by the related EntityBean to be loaded at the same time.

The same type of capability needs to be supported for CMR fields, finders and selects.
