from("direct:start")
    .loadBalance().sticky(header("myKey"))
        .to("seda:x")
        .to("seda:y")
        .to("seda:z")
    .end();

<route>
<from uri="direct:start"/>
    <loadBalance>
       <sticky>
           <correlationExpression>
               <header>myKey</header>
           </correlationExpression>
       </sticky>
       <to uri="seda:x"/>
       <to uri="seda:y"/>
