Sending parallel requests routed to a single endpoint using Apache Camel

Question

I get suggestions of Multicast,where a single request is routed to multiple endpoints as the snippet below.But the requirement is sending multiple requests in parallel to a single endpoint.

<route>
  <from uri="direct:start"/>
  <multicast>
    <to uri="mock:first"/>
    <to uri="mock:second"/>
    <to uri="mock:third"/>
  </multicast>
</route>

You can use parallelProcessing option.

<route>
  <from uri="direct:start"/>
  <multicast parallelProcessing="true">
    <to uri="mock:first"/>
    <to uri="mock:second"/>
    <to uri="mock:third"/>
  </multicast>
</route>
