<div dir="ltr">Yes; that assumption is wrong; in Spring-AMQP, ack mode AUTO means the container will automatically ack the message on completion.

<div>I have a spring amqp based application where the consumer is taking very long time to send acknowledgement. In RabbitMq management plugin, I see it in Unacknowledged state for almost a whole minute.I am currently testing this code by publishing only one
message. But my prefetch count and transaction size are a 50 and 30 respectively. Could this be any reason for the issue?</div>

<div>My consumer has heavy processing. But since it is in auto acknowledge mode, I believe, the message will be acknowledged immediately after the consumer receives it and before it start processing the message. Is this assumption wrong?</div>
