94% of codebase (in terms of filesize) are independent of JPA or JDO
spec-specified interfaces/classes. These are available in
openjpa-kernel/lib/jdbc package. The core kernel is subdivided into
object management (57%) and store management (37%) while object
managment being
independent of specific storage technology (a JDO legacy:).
6% code is JPA implementation following a facade pattern (available in
openjpa-persistence package) built on top of this kernel.

Subject: RE: Data + Query cache

(Performance pack is Kodo parlance, and this is a Kodo-related email.)

Actually, we're getting rid of Performance Pack altogether, at long
last, and replacing with a Professional Edition. (I never much liked the
Performance Pack name, given that the other two were editions.) I don't
remember the details of what lands where, but we aren't going to be
selling things that are available in OpenJPA.

You can get a feeling for what the JDO bindings for Kodo look like by
taking a look at the openjpa-persistence and openjpa-persistence-jdbc
modules in OpenJPA -- you'll notice that the bindings largely add spec
behavior to the core kernel. So the features available in the core
kernel are available to all bindings.
