<div dir="ltr">What about reject? The thing is, if there are multiple nodes of a worker that's consuming the message I want it that if a worker already read the message, it will not be possible to for it to be delivered to the other consumers so I am guessing ack will do this for me and reject will requeue it if my process fails.<div><br></div><div>Am I correct on this?</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, May 12, 2017 at 7:56 AM, Bastien CHAMAGNE <span dir="ltr"><<a href="mailto:bchamagne@idmog.com" target="_blank">bchamagne@idmog.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p>Hi Kareem, you should ack only when your application have
processed the message. See <a class="m_-8435364828102131017moz-txt-link-freetext" href="https://www.rabbitmq.com/confirms.html" target="_blank">https://www.rabbitmq.com/<wbr>confirms.html</a></p><div><div class="h5">

<div dir="ltr">Is it possible with RabbitMQ to consume a message

<div><br>
</div>
<div>Because let's say I consumed a message and started to
process it and half way through processing it the application
fails. I want to be able to re-process that message again. Is
it possible to not delete the message and delete it manually
after my process has successfully completed?</div>
<div><br>
</div>
<div>To avoid duplication, I plan to use a secondary database,
either Redis or Memcache to store the ID of the message to
ensure that it's not being processed by more than one
application.</div>

<div>Thanks!</div>
