It would be really nice if the EJB architecture handled the creation of
coarse-grained communication. That is, the beans are designed with
fine-grained property accessors, but the Application Assembler can declare
which properties are batched & cached by the remote proxy.
This could get tricky with the setter-methods, but very useful.

who claimed to do this - I think it was Gemstone)
4. My hack above
are all attacking different aspects of the same problem, namely the
granularity of object models vs the granularity of architected server-side
objects. The ideal solution, in my opinion, would be to allow every object
in the model to be an efficiently callable CMP "sub-entity bean" and to
compose sub-entities at deployment time into coarse-grained entity beans
working approximately as I described above. Unfortunately "sub-entity
beans" are not yet architected.
