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.
