Subject Re: Broker Federation with an Active-Active Broker Cluster
Date Thu, 07 Dec 2017 16:37:36 GMT
Hello Tim,

thank you. Now I got the difference.

As far as I understood the Artemis documentation it is possible to
configure a cluster and also connect single satellite brokers to this
cluster.

The satellite brokers can be connected using a bi-directional bridge so I
would use the core bridge and would use a network-connector where duplex is
set to true.

Is this a way I could go?

Kind Regards,
Andreas
