auto-create queue persistence and scale down behavior

["Steigerwald, Aaron" <as...@brandesassociates.com.INVALID>]

Hello,

Should empty auto-created queues and/or topics persist broker restarts with this setting?-

<address-setting match="#">
   <auto-delete-queues>false</auto-delete-queues>
   ...

It doesn't seem to in 2.21.0. Setting <auto-delete-addresses>false</auto-delete-addresses> seems to persist auto-created addresses but empty auto-created queues and topics are still deleted.

Also, setting <auto-delete-queues>false</auto-delete-queues> seems to prevent messages from scaling down to specified broker, which is server-connector-2-master in the following example-

      <ha-policy>
         <live-only>
            <scale-down>
               <connectors>
                  <connector-ref>server-connector-2-master</connector-ref>
               </connectors>
            </scale-down>
         </live-only>
      </ha-policy>

No logs are generated on server-connector-2-master when scale down occurs and <auto-delete-queues>false</auto-delete-queues> is set. It works as expected when set to true (the default).

Is this expected behavior?

Thank you,
