+ <body>
+ <h1>JBoss Messaging <br>JMS Message Consumer Rate Limiting</h1>
+ <br><br>
+ <p>With JBoss Messaging you can specify a maximum consume rate at which a JMS MessageConsumer will consume messages.
+ This can be specified when creating or deploying the connection factory. See <code>jbm-jms.xml</code></p>
+ <p>If this value is specified then JBoss Messaging will ensure that messages are never consumed at a rate higher than
+ the specified rate. This is a form of consumer <i>throttling</i>.</p>
+ <h2>Example step-by-step</h2>
+ <p>In this example we specify a <code>consumer-max-rate</code> of <code>10</code> messages per second in the <code>jbm-jms.xml</code>
+ file when deploying the connection factory:</p>
+ <pre>
+ <code>
+ <connection-factory name="ConnectionFactory">
+ <connector-ref connector-name="netty-connector"/>
+ <entries>
+ <entry name="ConnectionFactory"/>
+ </entries>
+
+ <!-- We limit consumers created on this connection factory to consume messages at a maximum rate
+ of 10 messages per sec -->
+ <consumer-max-rate>50</producer-max-rate>
+
+ </connection-factory>
+ </code>
+ </pre>
+ <p>We then simply consume as many messages as we can in 10 seconds and note how many messages are actually consumed.</p>
+ <p>We note that the number of messages consumed per second never exceeds the specified value of <code>10</code> messages per second.</p>
+ <br>
+ <p><i>To run the example, simply type <code>ant</code> from this directory</i></p>
+ <br>
+ <ol>
+ <li>Create an initial context to perform the JNDI lookup.</li>
+ <pre>
+ <code>initialContext = getContext(0);</code>
+ </pre>
+
+ <li>Perfom a lookup on the queue</li>
+ <pre>
+ <code>Queue queue = (Queue)initialContext.lookup("/queue/exampleQueue");</code>
+ </pre>
+
+ <li>Perform a lookup on the Connection Factory</li>
+ <pre>
+ <code>ConnectionFactory cf = (ConnectionFactory)initialContext.lookup("/ConnectionFactory");</code>
+ </pre>
+
+ <li>Create a JMS Connection</li>
+ <pre>
+ <code>connection = cf.createConnection();</code>
+ </pre>
+
+ <li>Create a JMS Session</li>
+ <pre>
+ <code>Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);</code>
+ </pre>
+
+ <li>Create a JMS MessageProducer</li>
+ <pre>
+ <code>MessageProducer producer = session.createProducer(queue);</code>
+ </pre>
+
+ <li>Create a JMS MessageConsumer</li>
+ <pre>
+ <code>MessageConsumer consumer = session.createConsumer(queue);</code>
+ </pre>
+
+ <li>Start the connection</li>
+
+ <pre>
+ <code>
+ connection.start();
+ </code>
+ </pre>
+
+
+ <li>Send a bunch of messages</li>
+ <pre>
+ <code>
+ final int numMessages = 150;
+
+ for (int i = 0; i < numMessages; i++)
+ {
+ TextMessage message = session.createTextMessage("This is text message: " + i);
+
+ producer.send(message);
+ }
+ </code>
+ </pre>
+
+ <li>Consume as many messages as we can in 10 seconds</li>
+
+ <pre>
+ <code>
+ final long duration = 10000;
+
+ int i = 0;
+
+ long start = System.currentTimeMillis();
+
+ while (System.currentTimeMillis() - start <= duration)
+ {
+ TextMessage message = (TextMessage)consumer.receive(2000);
+
+ if (message == null)
+ {
+ return false;
+ }
+
+ i++;
+ }
+
+ long end = System.currentTimeMillis();
+
+ double rate = 1000 * (double)i / (end - start);
+
+ System.out.println("We consumed " + i + " messages in " + (end - start) + " milliseconds");
+
+ System.out.println("Actual consume rate was " + rate + " messages per second");
+ </code>
+ </pre>
+
+ <li>This should produce output something like:</li>
+
+ <pre>
+ <code>
+ [java] Sent messages
+ [java] Will now try and consume as many as we can in 10 seconds ...
+ [java] We consumed 100 messages in 10001 milliseconds
+ [java] Actual consume rate was 9.99900009999 messages per second
+
+ </code>
+ </pre>
+
+ <li>Be sure to close our resources!</li>
+
+ <pre>
+ <code>
+ finally
+ {
+ if (initialContext != null)
+ {
+ initialContext.close();
+ }
+
+ if (connection != null)
+ {
+ connection.close();
+ }
+ }</code>
