Delay Interceptor

Available in Camel 1.5

The Delay interceptor is an route interceptor that is used for slowing processing of messages down. This allows you to enable this interceptor and set a fixed amount of delay between each step a message passes in the route path, to show how things is happening nice and slowly, so you are not bombarded with a zillion lines of logging output.

The delay interceptor can be configured as follows:

• setting the delay attribute in the spring camelContext tag.
• adding the delay interceptor to the CamelContext in Java code.

Configuring using Spring

Just set the delay attribute of the camelContext tag as shown below:

    <camelContext id="camel" delayer="500" xmlns="http://activemq.apache.org/camel/schema/spring">
        <route>
            <from uri="direct:start"/>
            <to uri="mock:result"/>
        </route>
    </camelContext>

Configuring using Java

You can add the delayer interceptor in the RouteBulder as shown below:

    public void configure() throws Exception {
        // add the delay interceptor to delay each step 200 millis
        getContext().addInterceptStrategy(new Delayer(200));

       ... // regular routes here
    }

In Camel 2.0 its a bit easier as you can just do

getContext().setDelayer(200);

Granularity

In Camel 2.0 you can configure it on both camel context and per route as you like. Per route will override the camel context setting.
For example the route below is only the first route that has a delayer with 200 millis.

<camelContext ...>

   <route delayer="200">
     ...
   </route>

   <route>
     ...
   </route>

</camelContext>
