Pub/Sub Communications
ZeroMQ can be used to bind a channel so that producers and consumers can connect to it remotely. In the following example, ProducerComposite and ConsumerComposite are deployed to different zones (they could also be deployed to the same zone). Fabric3 will transparently setup ZeroMQ pub/sub sockets and propagate the socket addresses so that the publisher and consumer can connect remotely:
The following excerpt shows how this channel binding is configured:
<composite name="ProducerComposite" ...>
<component name="TestProducer">
<implementation.java class="..."/>
<producer name="channel" target="TestChannel"/>
</component>
</composite>
<composite name="ChannelComposite"...>
<channel name="TestChannel">
<f3:binding.zeromq/>
</channel>
</composite>
<composite name="ConsumerComposite" ...>
<component name="TestConsumer">
<implementation.java class="..."/>
<consumer name="channel" source="TestChannel"/>
</component>
</composite>
