Example usage:
NSQLookup lookup = new DefaultNSQLookup();
lookup.addLookupAddress("localhost", 4161);
NSQConsumer consumer = new NSQConsumer(lookup, "speedtest", "dustin", (message) -> {
System.out.println("received: " + message);
//now mark the message as finished.
message.finished();
//or you could requeue it, which indicates a failure and puts it back on the queue.
//message.requeue();
});
consumer.start();
Example usage:
NSQProducer producer = new NSQProducer().addAddress("localhost", 4150).start();
producer.produce("TestTopic", ("this is a message").getBytes());
By default Backoff does not kick in and a consumer will eat all your memory and CPU. To enable Backoff you have to set your own thread pool executer with:
consumer.setExecutor(...);
