Daniel Keir Haywood commented on CAUSEWAY-3779:
-----------------------------------------------
Hmm, seems that I was mistaken, there is no general purpose DN API that will do
this efficiently.
the PersistenceManager#getObjectsById(Collection) ultimately seems to iterate
one by one (down in StorePersistenceHandler#findObjects(...) ).
So will likely have to roll-our-own if we want a performance improvement here.
