Hi,<div><br></div><div>I think the easiest would be to implement some kind of RPC logic so when the consumer gets the "banana" message, it can publish a message back to the sender so the sender can restart the sequence.</div>
<div><br></div><div>You could also try something with basic.nack and a bascic.qos of the number of messages that you want to cycle through. So in your case you can set a prefetch count of 3 and whenever you get the banana message you basick.nack all three. See <a href="http://www.rabbitmq.com/nack.html">http://www.rabbitmq.com/nack.html</a></div>
<div><br></div><div>The first approach could be more flexible. <span></span></div><div><br></div><div>Regards,</div><div><br></div><div>Alvaro<br><br>On Wednesday, November 27, 2013, <a href="mailto:yby538@163.com">yby538@163.com</a> wrote:<br>

<div>hi,all</div>
<div> </div>
<div>I have a sender and i have a receiver. Sender pushes the messages,
apple ,orange ,banana to queue which is named "fruit"</div>
<div> </div>
<div> once the receiver gets the message "banana" and send the ack. i
want the sender to be noticed so it can send the message "banana" to the
queue</div>
<div> </div>
<div> you know, i mean, i want to ensure that the queue does always
contains banana ,apple and orange and if one message was got by the receiver
,the sender will push it to the queue</div>
<div> </div>
<div> how to implement it, please?</div>
<div> </div>
<div>Does it make sense? i am very sorry since my English is very poor</div>
<div> </div>
<div> thanks a lot</div></div>
