ActiveMQ Artemis connection-router question

I'm trying to set up a broker with two connection routers to two different clusters using ROUND_ROBIN as the policy. However, when I start the broker, I'm getting this error:

AMQ214019: Invalid configuration

Caused by: org.xml.sax.SAXParseException; cvc-id.2: There are multiple occurrences of ID value 'ROUND_ROBIN'.

If I change the policy to any other non-duplicated value, the broker starts normally.

version 2.35.0

               <username>zzz</username>
               <password>ccc</password>
               <static-connectors>
                  <connector-ref>server3</connector-ref>
                  <connector-ref>server4</connector-ref>
               </static-connectors>
            </pool>
         </connection-router>

Is it possible to use one connection router broker for different clusters ?

Solution

  • This is a bug. I created the issue ARTEMIS-4951. The fix will be included in Apache ActiveMQ Artemis 2.36.0 which is due to be released in the next few weeks.
