Hmm, I would have thought the session cache would have instantiated one
instance of a storage engine for the entire idp, but it sounds like
you're saying it actually instantiates an instance for each individual
session? Or am I misunderstanding? I'm not quite sure what you mean by
session ID in this context. At least for the hazelcast storage backend,
each instance creates a hazelcast map, and creating a bunch of them
seems a lot less efficient than just creating one that's shared.
