Subject Re: [jira] Created: (OPENJPA-556) Data cache infrastructure should take advantage of batching
Date Fri, 04 Apr 2008 20:01:51 GMT
That's right, that the code here (transformToVersionSafePCDatas) should call
cache.containsAll() or cache.getAll().  That way, it will save a lot for any
data cache that provide getAll().  It won't gain much for OpanJPA "native"
data cache since it is delegated to AbstractDataCache.getAll() (ln. 449)
which loops thru the list to get the objects from the cache.  However, it
save the traffic if any.
