| <h1 id="diverting-and-splitting-message-flows">Diverting and Splitting Message Flows</h1> |
| <p>Apache ActiveMQ Artemis allows you to configure objects called <em>diverts</em> with some |
| simple server configuration.</p> |
| <p>Diverts allow you to transparently divert messages routed to one address |
| to some other address, without making any changes to any client |
| application logic.</p> |
| <p>Diverts can be <em>exclusive</em>, meaning that the message is diverted to the |
| new address, and does not go to the old address at all, or they can be |
| <em>non-exclusive</em> which means the message continues to go the old address, |
| and a <em>copy</em> of it is also sent to the new address. Non-exclusive |
| diverts can therefore be used for <em>splitting</em> message flows, e.g. there |
| may be a requirement to monitor every order sent to an order queue.</p> |
| <p>When an address has both exclusive and non-exclusive diverts configured, |
| the exclusive ones are processed first. If any of the exclusive diverts |
| diverted the message, the non-exclusive ones are not processed.</p> |
| <p>Diverts can also be configured to have an optional message filter. If |
| specified then only messages that match the filter will be diverted.</p> |
| <p>Diverts can apply a particular routing-type to the message, strip the |
| existing routing type, or simply pass the existing routing-type through. |
| This is useful in situations where the message may have its routing-type |
| set but you want to divert it to an address using a different routing-type. |
| It's important to keep in mind that a message with the <code>anycast</code> |
| routing-type will not actually be routed to queues using <code>multicast</code> and |
| vice-versa. By configuring the <code>routing-type</code> of the divert you have the |
| flexibility to deal with any situation. Valid values are <code>ANYCAST</code>, |
| <code>MULTICAST</code>, <code>PASS</code>, & <code>STRIP</code>. The default is <code>STRIP</code>.</p> |
| <p>Diverts can also be configured to apply a <a href="transformers.html"><code>Transformer</code></a>. |
| If specified, all diverted messages will have the opportunity of being |
| transformed by the <code>Transformer</code>. When an address has multiple diverts |
| configured, all of them receive the same, original message. This means that |
| the results of a transformer on a message are not directly available for |
| other diverts or their filters on the same address.</p> |
| <p>See the documentation on <a href="using-server.html">adding runtime dependencies</a> to |
| understand how to make your transformer available to the broker.</p> |
| <p>A divert will only divert a message to an address on the <em>same server</em>, |
| however, if you want to divert to an address on a different server, a |
| common pattern would be to divert to a local store-and-forward queue, |
| then set up a bridge which consumes from that queue and forwards to an |
| address on a different server.</p> |
| <p>Diverts are therefore a very sophisticated concept, which when combined |
| with bridges can be used to create interesting and complex routings. The |
| set of diverts on a server can be thought of as a type of routing table |
| for messages. Combining diverts with bridges allows you to create a |
| distributed network of reliable routing connections between multiple |
| geographically distributed servers, creating your global messaging mesh.</p> |
| <p>Diverts are defined as xml in the <code>broker.xml</code> file at the <code>core</code> attribute level. |
| There can be zero or more diverts in the file.</p> |
| <p>Diverted message gets a new message ID, and its address is set to a forward |
| address. To access original values, use message properties: original destination |
| is stored in a String property <code>_AMQ_ORIG_ADDRESS</code> (<code>Message.HDR_ORIGINAL_ADDRESS</code> |
| constant from the Core API), and the original message ID in a Long property |
| <code>_AMQ_ORIG_MESSAGE_ID</code> (<code>Message.HDR_ORIG_MESSAGE_ID</code> constant from the |
| Core API).</p> |
| <p>Please see the examples for a full working example showing you how to |
| configure and use diverts.</p> |
| <p>Let's take a look at some divert examples:</p> |
| <h2 id="exclusive-divert">Exclusive Divert</h2> |
| <p>Let's take a look at an exclusive divert. An exclusive divert diverts |
| all matching messages that are routed to the old address to the new |
| address. Matching messages do not get routed to the old address.</p> |
| <p>Here's some example xml configuration for an exclusive divert, it's |
| taken from the divert example:</p> |
| <pre><code class="lang-xml"><span class="hljs-tag"><<span class="hljs-name">divert</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"prices-divert"</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">address</span>></span>priceUpdates<span class="hljs-tag"></<span class="hljs-name">address</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">forwarding-address</span>></span>priceForwarding<span class="hljs-tag"></<span class="hljs-name">forwarding-address</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">filter</span> <span class="hljs-attr">string</span>=<span class="hljs-string">"office='New York'"</span>/></span> |
| <span class="hljs-tag"><<span class="hljs-name">transformer-class-name</span>></span> |
| org.apache.activemq.artemis.jms.example.AddForwardingTimeTransformer |
| <span class="hljs-tag"></<span class="hljs-name">transformer-class-name</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">exclusive</span>></span>true<span class="hljs-tag"></<span class="hljs-name">exclusive</span>></span> |
| <span class="hljs-tag"></<span class="hljs-name">divert</span>></span> |
| </code></pre> |
| <p>We define a divert called <code>prices-divert</code> that will divert any |
| messages sent to the address <code>priceUpdates</code> to another local address |
| <code>priceForwarding</code>.</p> |
| <p>We also specify a message filter string so only messages with the |
| message property <code>office</code> with value <code>New York</code> will get diverted, all |
| other messages will continue to be routed to the normal address. The |
| filter string is optional, if not specified then all messages will be |
| considered matched.</p> |
| <p>In this example a transformer class is specified without any configuration |
| properties. Again this is optional, and if specified the transformer will |
| be executed for each matching message. This allows you to change the |
| messages body or properties before it is diverted. In this example the |
| transformer simply adds a header that records the time the divert happened. |
| See the <a href="transformers.html">transformer chapter</a> for more details about |
| transformer-specific configuration.</p> |
| <p>This example is actually diverting messages to a local store and forward |
| queue, which is configured with a bridge which forwards the message to |
| an address on another ActiveMQ Artemis server. Please see the example for |
| more details.</p> |
| <h2 id="non-exclusive-divert">Non-exclusive Divert</h2> |
| <p>Now we'll take a look at a non-exclusive divert. Non exclusive diverts |
| are the same as exclusive diverts, but they only forward a <em>copy</em> of the |
| message to the new address. The original message continues to the old |
| address</p> |
| <p>You can therefore think of non-exclusive diverts as <em>splitting</em> a |
| message flow.</p> |
| <p>Non exclusive diverts can be configured in the same way as exclusive |
| diverts with an optional filter and transformer, here's an example |
| non-exclusive divert, again from the divert example:</p> |
| <pre><code class="lang-xml"><span class="hljs-tag"><<span class="hljs-name">divert</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"order-divert"</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">address</span>></span>orders<span class="hljs-tag"></<span class="hljs-name">address</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">forwarding-address</span>></span>spyTopic<span class="hljs-tag"></<span class="hljs-name">forwarding-address</span>></span> |
| <span class="hljs-tag"><<span class="hljs-name">exclusive</span>></span>false<span class="hljs-tag"></<span class="hljs-name">exclusive</span>></span> |
| <span class="hljs-tag"></<span class="hljs-name">divert</span>></span> |
| </code></pre> |
| <p>The above divert example takes a copy of every message sent to the |
| address '<code>orders</code>' and sends it to a local address called |
| '<code>spyTopic</code>'.</p> |
