This is useful when receiving messages from external ZeroMQ publishes that send multi-frame messages.
Performance Considerations
When using the ZeroMQ binding with channels, it is strongly recommended to use ring buffer channels as described in the next section. Ring buffer channels provide low contention and allow business logic to be isolated on a thread that is separate from IO operations. If ring buffer channels are not used (i.e. default channels), ZeroMQ consumers will be invoked on the same thread as the socket read. In some situations, this may be the desired result and perform adequately.
In addition, it is highly recommended to use the bytecode proxy generation extension (Maven coordinates: org.codehaus.fabric3:fabric3-bytecode-proxy) to avoid the overhead and object creation associated with JDK proxies.
