II. RabbitMq Queue Durability and Persistent MessageDelivery

RabbitMq Queue has 2 kind of durability: {Durable, Transient}.

Durable queue is a solution for re-declared persistent messages during broker restarts if broker is taken down.

Scenarios with above design:

When sending 2 messages {a persistent message, a trasient message} to exchange X, all messages will be delivered to 2 queues {Q1, Q2}.
Stop RabbitMq service, then re-start it -> just a persistent message will be re-declared in durable queue Q1.

With Spring framework, default message is PERSISTENT mode:


package org.springframework.amqp.core;
...

public class MessageProperties implements Serializable {
    ...
    
    public static final MessageDeliveryMode DEFAULT_DELIVERY_MODE = MessageDeliveryMode.PERSISTENT;
    ...
    
}

We can change the delivery mode as below:
