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.
