[jira] Updated: (OPENJPA-263) Introducing getAll(List) method for data cache to be called by loadAll() will allow data cache plug-ins to leverage the advantage of any third-party cache that provides a way to get multiple object in one call by providing a list of keys (oids).

> OpenJPA: 5 files to be donated to OpenJPA: (changed, no new file)
> There are changes to the following 5 files which will be donated to OpenJPA 
> to be able to leverage ObjectGrid map agent to improve the performance on 
> getting the relationship loaded.
> (the donation is upon the approval of OpenJPA committee)
> - org.apache.openjpa.datacache:
> o     AbstractPCData:
>      toField: calling toNestedFields(new) instead of looping thru all 
> elements in the field
> (Implements the Collection only for now, may need to apply it to Map and 
> Array)
>      toNestedFields: (new)
>      toRelationFields: (new) calls findAll()
> - org.apache.openjpa.datacache:
> o     DataCacheStoreManager: enhance loadAll() to issue getAll() instead get()
> o     AbstractDataCache: add getAll() to abstract as default
> o     DataCache: add getAll() to interface
> o     DelegatingDataCache: add getAll() delegation
> (Please see detail information in the attached Word document.)
