The total maximum size of - messages in bytes that will be buffered on each consumer is determined by the <code>consumer-window-size</code> - parameter on the connection factory.</p> - <p>In some cases it is not desirable to buffer any messages on the client side consumer.</p> - <p>An example would be an order queue which had multiple consumers that processed orders from the queue. - Each order takes a significant time to process, but each one should be processed in a timely fashion.</p> - <p>If orders were buffered in each consumer, and a new consumer was added that consumer would not be able - to process orders which were already in the client side buffer of another consumer.</p> - <p>To turn off client side buffering of messages, set <code>consumer-window-size</code> to zero.</p> - - <p>With ActiveMQ Artemis 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>activemq-jms.xml</code></p> - <h2>Example step-by-step</h2> - <p>In this example we specify a <code>consumer-window-size</code> of <code>0</code> bytes in the <code>activemq-jms.xml</code> - file when deploying the connection factory:</p> - <pre class="prettyprint"> - <code> - <connection-factory name="ConnectionFactory"> - <connector-ref connector-name="netty-connector"/> - <entries> - <entry name="ConnectionFactory"/> - </entries> - - <!-- We set the consumer window size to 0, which means messages are not buffered at all - on the client side --> - <consumer-window-size>0</consumer-window-size> - - </connection-factory> - </code> - </pre> - <p>We create a consumer on a queue and send 10 messages to it. We then create another consumer on - the same queue.</p> - <p>We then consume messages from each consumer in a semi-random order. We note that the messages - are consumed in the order they were sent.</p> - <p>If the messages had been buffered in each consumer they would not be available to be consumed - in an order determined afer delivery.</p> - - <ol> - <li>Create an initial context to perform the JNDI lookup.</li> - <pre class="prettyprint"> - <code>initialContext = getContext(0);</code> - </pre> - - <li>Perfom a lookup on the queue</li> - <pre class="prettyprint"> - <code>Queue queue = (Queue)initialContext.lookup("/queue/exampleQueue");</code> - </pre> - - <li>Perform a lookup on the Connection Factory</li> - <pre class="prettyprint"> - <code>ConnectionFactory cf = (ConnectionFactory)initialContext.lookup("/ConnectionFactory");</code> - </pre> - - <li>Create a JMS Connection</li> - <pre class="prettyprint"> - <code>connection = cf.createConnection();</code> - </pre> - - <li>Create a JMS Session</li> - <pre class="prettyprint"> - <code>Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);</code> - </pre> - - <li>Create a JMS MessageProducer</li> - <pre class="prettyprint"> - <code>MessageProducer producer = session.createProducer(queue);</code> - </pre> - - <li>Create a JMS MessageConsumer</li> - <pre class="prettyprint"> - <code>MessageConsumer consumer1 = session.createConsumer(queue);</code> - </pre> - - <li>Start the connection</li> - - <pre class="prettyprint"> - <code> - connection.start(); - </code> - </pre> - - - <li>Send 10 messages to the queue</li> - <pre class="prettyprint"> - <code> - final int numMessages = 10; - - for (int i = 0; i < numMessages; i++) - { - TextMessage message = session.createTextMessage("This is text message: " + i); - - producer.send(message); - } - </code> - </pre> - - <li>Create another JMS MessageConsumer on the same queue.</li> - <pre class="prettyprint"> - <code>MessageConsumer consumer2 = session.createConsumer(queue);</code> - </pre> - - <li>Consume three messages from consumer2</li> - - <pre class="prettyprint"> - <code> - for (int i = 0; i < 3; i++) - { - TextMessage message = (TextMessage)consumer2.receive(2000); - - System.out.println("Consumed message from consumer2: " + message.getText()); - } - </code> - </pre> - - <li>Consume five messages from consumer1</li> - - <pre class="prettyprint"> - <code> - for (int i = 0; i < 5; i++) - { - TextMessage message = (TextMessage)consumer1.receive(2000); - - System.out.println("Consumed message from consumer1: " + message.getText()); - } - </code> - </pre> - - <li>Consume two more messages from consumer2</li> - - <pre class="prettyprint"> - <code> - for (int i = 0; i < 2; i++) - { - TextMessage message = (TextMessage)consumer1.receive(2000); - - System.out.println("Consumed message from consumer2: " + message.getText()); - } - </code> - </pre> - - - <li>Be sure to close our resources!</li> - - <pre class="prettyprint"> - <code> - finally - { - if (initialContext != null) - { - initialContext.close(); - } - - if (connection != null) - { - connection.close(); - } - }</code> - </pre> - </ol> - - <h2>More information</h2> - - <ul> - <li>User Manual's <a href="../../../docs/user-manual/en/html_single/index.html#flow-control.consumer.window">Consumer Window-Based Flow Control chapter</a></li> - </ul> - - </body> -</html>
