RabbitMQ Confirm Mechanism Explained

RabbitMQ’s confirm mechanism is used to ensure that messages have been successfully delivered to a queue, thus avoiding the risk of message loss. When a producer sends a message to a queue, they can set the message’s confirm mode to true, so RabbitMQ will return a confirmation message to the producer, informing them that the message has been successfully received and delivered to the queue. This allows the producer to ensure that the message will not be lost and continue with subsequent operations. If the message fails to send or is rejected, RabbitMQ will also return a corresponding confirmation message to the producer. By using the confirm mechanism, reliability and consistency of messages can be improved.
