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

<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>
