Hi all,
When Bela and I were discussing this issue I documented all the ideas
and questions on the jira issue. Please see
http://jira.jboss.com/jira/browse/JBCACHE-270
Bela is right we need to get a notification interceptor in place "Even
if we end up having only 95% of all notifications emitted from the
interceptor, and the rest directly, that would be fine too."
At the time thinking of this feature, I was debating another idea which
is having a dual notification interceptor. One to emits pre-call
notification at the bottom of the stack and one emits post-call at the
top of the stack. I can't recall why we didn't go with it. Anyway, I'm
bringing it up right now just to kick start the thinking process again.
Cheers,
Hany

Let's find the bits and pieces of emails between us and Hany, we
discussed this feature in great detail. IIRC, one of the issues was
that there was no real good place for the NotificationInterceptor,
in some cases towards the top would have been okay, in some not.
Example: CacheLoader/Store interceptor: those methods don't get
passed up, so a NotifInt towards the top would not be able to catch
them.
But, yes, we need to start thinking about having all notifications
emitted from one place, so let's kick-start that thought process
again. Even if we end up having only 95% of all notifications
emitted from the interceptor, and the rest directly, that would be
fine too.
Manik, maybe it is a good idea to involve Hany again, because he
was involved real deep before... I'm sure he remembers some of the
discussions...
