How to add re delivery delay in WSO2 Message Broker like ActiveMQ

Question

I have successfully configured the WSO2 Message Broker with my WSO2 ESB. I have also implemented successfully the JMS Transactions. It means that if there is an error in Service Normal Flow, Message will be rolledback.

Problem:

Previously i have configured the ActiveMq with my ESB. In that Setup i have a configuration in {ESB_HOME}/repository/conf/axis2/axis2.xml. This configuration donates the "Re-delivery Delay". This time is used to tell the MessageBroker(ActiveMQ) that when you are attempting to redeliver the message, you have to wait for this time before trying again.

<parameter name="redeliveryPolicy.redeliveryDelay" locked="true">1200000</parameter>

WSO2 Message Broker:

I want to achieve the same result in WSO2 Message Broker. I think it had to do with some configuration in {MB_HOME}/repository/conf/advanced/andes-config.xml. But i am unable to find that particular configuration setting anywhere in Message Broker.

Note: I am using WSO2 ESB 4.8.1 and WSO2 Message Broker 2.2.0.

What i want to achieve:

My goal is that i should be able to tell WSO2 Message Broker like ActiveMQ that you must take this much time before trying to re-deliver the message.

As I know it cannot be done like this in case of WSO2 MB. You have to setup a message store and a message processor guarding on that message store. And when you have a message processor it can be configured with interval and max delivery attempts.

(Alternatively, you can setup the maxAckWaitTime, it means it will wait at least 'maxAckWaitTime' seconds between two redelivery attempts)
