Is message lost when there's n/w issue while publishing the message to RabbitMQ?

I am using Spring AMQP to publish messages to RabbitMQ. Consider a scenario:
1. Java client sends a message to MQ usin amqpTemplate.convertAndSend()
2. But RabbitMQ is down OR there's some n/w issue

In this case the message will be lost? OR Is there any way it'll be persisted and will be retried?

I checked the publish-confirm model as well but as I understood, ultimately we've to handle the nack messages through coding on our own.

Solution

  • The RabbitTemplate supports adding a RetryTemplate which can be configured whit whatever retry semantics you want. It will handle situations when the broker is down.

    See Adding Retry Capabilities.

    You can use a transaction or publisher confirms to ensure rabbit secured the message.
