18.7. The Remote Cache Store

The RemoteCacheStore is an implementation of the cache loader that stores data in a remote Red Hat JBoss Data Grid cluster. The RemoteCacheStore uses the Hot Rod client-server architecture to communicate with the remote cluster.
For remote cache stores, Hot Rod provides load balancing, fault tolerance and the ability to fine tune the connection between the RemoteCacheStore and the cluster.

18.7.3. Define the Outbound Socket for the Remote Cache Store

The Hot Rod server used by the remote cache store is defined using the outbound-socket-binding element in a standalone.xml file.
An example of this configuration in the standalone.xml file is as follows:

Example 18.1. Define the Outbound Socket

Copy to Clipboard Toggle word wrap 
<server>
    <!-- Additional configuration elements here -->
    <socket-binding-group name="standard-sockets" 
    			  default-interface="public" 
    			  port-offset="${jboss.socket.binding.port-offset:0}">
        <!-- Additional configuration elements here -->
        <outbound-socket-binding name="remote-store-hotrod-server">
            <remote-destination host="remote-host" 
                                port="11222"/>
        </outbound-socket-binding>
    </socket-binding-group>
</server>
