<h1>JMS Message Consumer 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 consume rate at which a JMS MessageConsumer will consume messages.
|
|
This can be specified when creating or configuring the connection factory. See <code>jndi.properties</code>.</p>
|
|
<p>If this value is specified then ActiveMQ Artemis 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>jndi.properties</code>
|
|
file when configuring the connection factory:</p>
|
|
<pre class="prettyprint">
|
|
<code>
|
|
connectionFactory.ConnectionFactory=tcp://localhost:61616?consumerMaxRate=10
|
|
</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>
