- <h1>No Consumer Buffering Example</h1>
-
- <pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
-
-
- <p>By default, ActiveMQ Artemis consumers buffer messages from the server in a client side buffer
- before actual delivery actually occurs.</p>
- <p>This improves performance since otherwise every time you called receive() or had processed the last
- message in a MessageListener onMessage() method, the ActiveMQ Artemis client would have to go the
- server to request the next message involving a network round trip for every message reducing performance.</p>
- <p>Therefore, by default, ActiveMQ Artemis pre-fetches messages into a buffer on each consumer. 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>

- <h1>Paging Example</h1>
-
- <pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
-
-
- <p>This example shows how ActiveMQ Artemis would avoid running out of memory resources by paging messages.</p>
- <p>A maxSize can be specified per Destination via the destinations settings configuration file (broker.xml).</p>
- <p>When messages routed to an address exceed the specified maxSize the server will begin to write messages to the file
- system, this is called paging. This will continue to occur until messages have been delivered to consumers and subsequently
- acknowledged freeing up memory. Messages will then be read from the file system , i.e. depaged, and routed as normal. </p>
- <p>Acknowledgement plays an important factor on paging as messages will stay on the file system until the memory is released
- so it is important to make sure that the client acknowledges its messages.</p>
-
-
- <h2>Example step-by-step</h2>
-
- <ol>
- <li>First we need to get an initial context so we can look-up the JMS connection factory and destination objects from JNDI. This initial context will get it's properties from the <code>client-jndi.properties</code> file in the directory <code>../common/config</code></li>
- <pre class="prettyprint">
- <code>InitialContext initialContext = getContext();</code>
- </pre>
-
- <li>We look-up the JMS connection factory object from JNDI</li>
- <pre class="prettyprint">
- <code>ConnectionFactory cf = (ConnectionFactory) initialContext.lookup("/ConnectionFactory");</code>
- </pre>
-
- <li>We look-up the JMS queue object from JNDI. pagingQueue is configured to hold a very limited number of bytes in memory</li>
- <pre class="prettyprint">
- <code>Queue pageQueue = (Queue) initialContext.lookup("/queue/pagingQueue");</code>
- </pre>
-
- <li>We look-up the JMS queue object from JNDI.</li>
- <pre class="prettyprint">
- <code>Queue queue = (Queue) initialContext.lookup("/queue/exampleQueue");</code>
- </pre>
-
- <li>We create a JMS connection</li>
- <pre class="prettyprint">
- <code>connection = cf.createConnection();</code>
- </pre>
-
- <li>We create a JMS session. The session is created as non transacted. We will use client acknowledgement on this example.</li>
- <pre class="prettyprint">
- <code>Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);</code>
- </pre>
-
-
- <li>Create a JMS Message Producer for pageQueueAddress</li>
- <pre class="prettyprint"><code>
- MessageProducer pageMessageProducer = session.createProducer(pageQueue);
- </pre></code>
-
- <li>We don't need persistent messages in order to use paging. (This step is optional)</li>
- <pre class="prettyprint"><code>
- pageMessageProducer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
- </pre></code>
-
- <li>Create a Binary Bytes Message with 10K arbitrary bytes</li>
- <pre class="prettyprint"><code>
- BytesMessage message = session.createBytesMessage();
- message.writeBytes(new byte[10 * 1024]);
- </pre></code>
-
-
- <li>Send only 20 messages to the Queue. This will be already enough for pagingQueue. Look at ./paging/config/activemq-queues.xml for the config.</li>
- <pre class="prettyprint"><code>
- for (int i = 0; i < 20; i++)
- {
- pageMessageProducer.send(message);
- }
- </pre></code>
-
- <li>Create a JMS Message Producer</li>
- <pre class="prettyprint"><code>
- MessageProducer messageProducer = session.createProducer(queue);
- </pre></code>
-
- <li>We don't need persistent messages in order to use paging. (This step is optional)</li>
- <pre class="prettyprint"><code>
- messageProducer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
- </pre></code>
-
- <li>Send the message for about 30K, which should be over the memory limit imposed by the server</li>
- <pre class="prettyprint"><code>
- for (int i = 0; i < 30000; i++)
- {
- messageProducer.send(message);
- }
- </pre></code>
-
- <li>if you pause the example here, you will several files under ./build/data/paging</li>
-
- <pre class="prettyprint"><code>
- // Thread.sleep(30000); // if you want to just our of curiosity, you can sleep here and inspect the created files just for
- </pre></code>
-
-
- <li>Create a JMS Message Consumer</li>
- <pre class="prettyprint"><code>
- MessageConsumer messageConsumer = session.createConsumer(queue);
- </pre></code>
-
-
- <li>Start the JMS Connection. This step will activate the subscribers to receive messages.</li>
- <pre class="prettyprint"><code>
- connection.start();
- </pre></code>
-
-
- <li>Receive the messages. It's important to ACK for messages as ActiveMQ Artemis will not read messages from paging until messages are ACKed</li>
-
- <pre class="prettyprint"><code>
- for (int i = 0; i < 30000; i++)
- {
- message = (BytesMessage)messageConsumer.receive(1000);
-
- if (i % 1000 == 0)
- {
- System.out.println("Received " + i + " messages");
-
- message.acknowledge();
- }
- }
- </pre></code>
-
- <li>Receive the messages from the Queue names pageQueue. Create the proper consumer for that.</li>
- <pre class="prettyprint"><code>
- messageConsumer.close();
- messageConsumer = session.createConsumer(pageQueue);
-
- for (int i = 0; i < 20; i++)
- {
- message = (BytesMessage)messageConsumer.receive(1000);
-
- System.out.println("Received message " + i + " from pageQueue");
-
- message.acknowledge();
- }
- </pre></code>
-
- <li>And finally, <b>always</b> remember to close your JMS connections and resources after use, in a <code>finally</code> block. Closing a JMS connection will automatically close all of its sessions, consumers, producer and browser objects</li>
-
- <pre class="prettyprint">
- <code>finally
- {
- if (initialContext != null)
- {
- initialContext.close();
- }

- <p>Standard JMS supports three acknowledgement modes: AUTO_ACKNOWLEDGE, CLIENT_ACKNOWLEDGE, and
- DUPS_OK_ACKNOWLEDGE. For a full description on these modes please consult the JMS specification, or any
- JMS tutorial.</p>
- <p>All of these standard modes involve sending acknowledgements from the client to the server. However
- in some cases, you really don't mind losing messages in event of failure, so it would make sense
- to acknowledge the message on the server <b>before</b> delivering it to the client.</p>
- <p>By acknowledging the message before sending to the client, you can avoid extra network traffic and CPU
- work done in sending acknowledgements from client to server.</p>
- <p>The down-side of acknowledging on the server before delivery, is that if the system crashes after acknowledging
- the message, but before the message has been received by the client, then, on recovery, that message
- will be lost. This makes pre-acknowledgement not appropriate for all use cases, but it is very useful for some
- use-cases when you can cope with such loss of messages<p>
- <p>An example of a use-case where it might be a good idea to use pre-acknowledge, is for stock price update
- messages. With these messages it might be ok to lose a message in event of crash, since the next price
- update message will arrive soon, overriding the previous price.</p>
- <p>In order to use pre-acknowledge functionality with ActiveMQ Artemis the session has to be created with
- a special, ActiveMQ Artemis specific acknowledgement mode, given by the value of
- <code>ActiveMQJMSConstants.PRE_ACKNOWLEDGE</code>.
- <h2>Example step-by-step</h2>
-
- <ol>
- <li>Create an initial context to perform the JNDI lookup.</li>
- <pre class="prettyprint">
- <code>
- initialContext = getContext(0);
- </code>
- </pre>
-
- <li>Perform the look-ups</li>
- <pre class="prettyprint">
- <code>
- Queue queue = (Queue)initialContext.lookup("/queue/exampleQueue");
-
- ConnectionFactory cf = (ConnectionFactory)initialContext.lookup("/ConnectionFactory");
- </code>
- </pre>
-
- <li>Create a the JMS objects.</li>
- <pre class="prettyprint">
- <code>
- connection = cf.createConnection();
-
- Session session = connection.createSession(false, ActiveMQSession.PRE_ACKNOWLEDGE);
-
- MessageProducer producer = session.createProducer(queue);
-
- MessageConsumer messageConsumer = session.createConsumer(queue);
- </code>
- </pre>
-
- <li>Create and send a message.</li>
- <pre class="prettyprint">
- <code>
- TextMessage message1 = session.createTextMessage("This is a text message 1");
-
- producer.send(message1);
-
- System.out.println("Sent message: " + message1.getText());
- </code>
- </pre>
-
- <li>Print out the message count of the queue. The queue contains one message as expected
- delivery has not yet started on the queue.</li>
- <pre class="prettyprint">
- <code>
- int count = getMessageCount(connection);
-
- System.out.println("Queue message count is " + count);
- </code>
- </pre>
-
- <li>Start the Connection, delivery will now start. Give a little time for delivery to occur.</li>
- <pre class="prettyprint">
- <code>
- connection.start();
-
- Thread.sleep(1000);
- </code>
- </pre>
-
- <li>Print out the message count of the queue. It should now be zero, since the message has
- already been acknowledged even before the consumer has received it.</li>
- <pre class="prettyprint">
- <code>
- count = getMessageCount(connection);
-
- System.out.println("Queue message count is now " + count);
- </code>
- </pre>
-
- <li>Finally, receive the message.</li>
- <pre class="prettyprint">
- <code>
- TextMessage messageReceived = (TextMessage)messageConsumer.receive(5000);
-
- System.out.println("Received message: " + messageReceived.getText());
- </code>
- </pre>
-
- <li>Be sure to close our resources!</li>
- <pre class="prettyprint">
- <code>
- if (initialContext != null)

- <h1>JMS Message Producer Rate Limiting</h1>
-
- <pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
-
-
- <p>With ActiveMQ Artemis you can specify a maximum send rate at which a JMS MessageProducer will send messages.
- This can be specified when creating or deploying the connection factory. See <code>activemq-jms.xml</code></p>
- <p>If this value is specified then ActiveMQ Artemis will ensure that messages are never produced at a rate higher than
- specified. This is a form of producer <i>throttling</i>.</p>
- <h2>Example step-by-step</h2>
- <p>In this example we specify a <code>producer-max-rate</code> of <code>50</code> messages per second 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 limit producers created on this connection factory to produce messages at a maximum rate
- of 50 messages per sec -->
- <producer-max-rate>50</producer-max-rate>
-
- </connection-factory>
- </code>
- </pre>
- <p>We then simply send as many messages as we can in 10 seconds and note how many messages are actually sent.</p>
- <p>We note that the number of messages sent per second never exceeds the specified value of <code>50</code> messages per second.</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>

-
- <li>Create a JMS Connection</li>
- <pre class="prettyprint">
- <code>connection = cf.createConnection();</code>

-
- <li>Create a JMS Session</li>
- <pre class="prettyprint">
- <code>Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);</code>
- </pre>
-
- <li>Create a JMS Message Producer</li>
- <pre class="prettyprint">
- <code>MessageProducer producer = session.createProducer(queue);</code>
- </pre>
-
- <li>Send as many messages as we can in 10 seconds</li>
- <pre class="prettyprint">
- <code>

- int i = 0;

- long start = System.currentTimeMillis();

- System.out.println("We sent " + i + " messages in " + (end - start) + " milliseconds");
-
- System.out.println("Actual send rate was " + rate + " messages per second");
- </code>
- </pre>
-
- <li>We note that the sending rate doesn't exceed 50 messages per second. Here's some example output from a real
- run</li>
-
- <pre class="prettyprint">
- <code>
- [java] Will now send as many messages as we can in 10 seconds...
- [java] We sent 500 messages in 10072 milliseconds
- [java] Actual send rate was 49.64257347100874 messages per second
- </code>
