WildFly HornetQ Cluster Connection Configuration

Internal

• WildFly HornetQ-Based Messaging Subsystem Configuration

Overview

A cluster connections represents an unidirectional communication channel between nodes. More details about the cluster connection concepts are available here: Cluster Connection Concepts. It is configured as follows:

<subsystem xmlns="urn:jboss:domain:messaging:1.4">
  <hornetq-server name="active-hq-node">
    ...
    <cluster-connections>
      <cluster-connection name="load-balancing-to-lb2">
        <address>jms</address>
        <connector-ref>netty-inbound</connector-ref>
        <retry-interval>500</retry-interval>
        <use-duplicate-detection>true</use-duplicate-detection>
        <forward-when-no-consumers>true</forward-when-no-consumers>
        <max-hops>1</max-hops>
        <static-connectors>
          <connector-ref>
            load-balancing-node-lb2
          </connector-ref>
        </static-connectors>
      </cluster-connection>
    </cluster-connections>
   ...
   </hornetq-server>
</subsystem>

Configuration Elements

address

Each cluster connection only applies to messages sent to an address that starts with this value. The address can be any value and you can have many cluster connections with different values of addresses, simultaneously balancing messages for those addresses, potentially to different clusters of servers. This does not use wild card matching

max-hops

In symmetric clusters, max-hops must be set to 1.
