Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the asciidoc in the repository:

How to send the same message to multiple endpoints

When you need to send the same message to multiple endpoints then you should use Multicast.

In the sample below we consume messages from the activemq queue foo and want to send the same message to both seda:foo and seda:bar. Sending the same message requires that we use Multicast. This is done by adding the multicast() before the to type:

from("activemq:queue:foo").multicast().to("seda:foo", "seda:bar");

Pipeline is default in Camel

If you have a route such as:

from("activemq:queue:foo").to("seda:foo", "seda:bar");

It is default a pipeline in Camel (that is the opposite to Multicast). In the above example using pipes and filters then the result from seda:foo is sent to seda:bar, ie. its not the same message sent to multiple destinations, but a sent through a chain (the pipes and the filters).
