dynamic separate clusters

[dtravin]

Hi all,

Is there a way to create separate clusters dynamically ?
Something like Hazelcast.getCluster("cluster"+getSomeEntityId()).

I have 1 server that creates logical groups and peers members of
different groups do not communicate with each other.
I want to minimize traffic.

Yes. You should use HazelcastInstance instead of Hazelcast singleton.

Config cluster1Config= new XmlConfigBuilder().build();
cluster1Config.getGroupConfig().setName("cluster1");
HazelcastInstance h1 = Hazelcast.newHazelcastInstance(cluster1Config);

Config cluster2Config= new XmlConfigBuilder().build();
cluster2Config.getGroupConfig().setName("cluster2");
HazelcastInstance h2 = Hazelcast.newHazelcastInstance(cluster2Config);

h1 and h2 now belong to different clusters because they have different
group name (cluster name).

Thanks. That is clear.

How about authentication/authorization?
Basically, I want to add some more fields in JoinRequest class and
handle them in ClusterManager.
However, ClusterManager is final I cannot see elegant solution.
I also need more fields in MemberInfo (not only address but some
application specific info)
JAAS is what I need, but probably it could be done simplier with a
couple of hacks.

What would you suggest in this situation?

I am second on flexible authentication/authorization.
