I'm totally agree with Chris.
Ioannis and I are aware that the solution is not the killer one, that we
can do a lot of things better.
However, the solution has the main advantage to exist and work.
People (Karaf contributors and community) can play with this cluster
implementation and enhance it.
So here's my +1 also.

JB

+1 for bringing this code to Karaf.
I haven't tested this out thoroughly or even looked deeply at the
code, but in general I like this idea. I certainly agree with some of
Guillaume's points, however unless there is a suitable alternative I
think this will provide a good starting point for the community to get
involved and improve it.

Guillaume, I haven't seen all your points, so here are some comments for the
rest:
*Automatic discovery is really a myth imho. Such protocols have to use
multicast and multicast is really forbidden in a lot of places. So
*relying* on multicast would be a mistake I think. I've seen
hazelcast can be configured using static ips which sounds better
(though multicast is nice for demos, no problem with that).*
In places like EC2 or other Cloud platforms, indeed multicast is forbidden,
but in a private cluster, multicast is great.
So I would say that automatic discovery is not panacea, but its still a very
strong feature.
*That's really my problem. Maybe it's a misunderstanding, but when you*
* say "replication", I hear same thing everywhere, which I have a
problem with.
I think that definitely solve some problems, but it looks too limited.*
Let's don't stick to the "term" replication. Let's just say that it provides
means to configure a group of nodes instead of a single one. And note that
not all nodes are in total synch. You can configure what you want to sync.
The configuration means can be extended and become more granular in order to
fit all needs.
