Kurt Stam commented on JBESB-823:
---------------------------------

K: Yeah I agree. So I added a new column called 'classification', which basically enables use to have more types of stores, rather then setting up different db schemas (or even tables).
The different types are STORE (this is store as intended), and I added DLQ and RDLVR. So they function independently from one another. Does that answer your question?

M: Sort of: I think that addresses the back-end implementation issue. But I was wondering about separate services: they may get configured to be the same implementation, but from a users perspective they could still remain separate. That way if someone wants to have a separate MessageStore because of security implications, we can support that.

K:The only problem is that we only have one place to configure the store credentials which is in the jbossesb-properties.xml. A while ago a figured we should move it out and put it with the
service configuration, but since there was no real hard reason to make clutter up the service configuration I left it as it was. So it's a config issue only. That said you could run different stores on different nodes and get around it that way.

M:OK, so it's possible at the moment, just not ideal. I'll add a JIRA task so we don't forget this conversation and then we can get back to it in a later revision.

K:Sounds good. Or you can make the messageStore use the JCR, and the DLQ/RDLVR the DBimpl.

> The Message Store was intended to logging, debugging etc. It keeps track of what's on the wire. We're now using it for the retry/retransmit and DLQ. Even if the same backend implementation were used, shouldn't that be a separate service? DLQ is for reliability, whereas the Message Store implementation isn't necessarily reliable or available to users, e.g., an organisation may not want to expose it's Message Store details to the world for security reasons, but a general DLQ may be supported by the ESB for reliability reasons.
