<pre wrap="">Hi thanks for the answer, but it is not what I'm looking for.
I don't want to drop any messages, because my producer is faster than
consumer, but not all the time and all the data is necessary.There is time
when it doesn't produce any messages. I don't want to have any other buffer
of course, but RabbitMQ doesn't let my producer to sending messages even if
there is a lot of free memory. I'm asking how can I setup RabbitMQ to remove
that buffer. My server hardware is 32 CPUs and 64 GB RAM, I don't think I
need better hardware, because even if I store about 8 millions messages
which takes about 600 bytes (everyone) than it turn on horrible flow control
which prevents sending as fast as I need. Please tell me how can I turn off
flow control. My application wants to queued messages on RabbitMQ server in
its memory not disk and I don't want to be prevented by RabbitMQ sending by
producer or consuming messages by the consumer.</pre>

If you need to store an unbounded number of messages in the queue,
then as i see it, you've got two options:<br>
<ol>
<li>Use the rabbitmq-toke plugin, which allows messages to be
stored in tokyo cabinet. That said, I don't know how well
supported and/or documented that is. </li>
<li>Use another queue server, such as bitly's nsq, beanstalkd, or
even Kafka.<br>
</li>
</ol>
<p>Assuming that you've got very basic requirements in terms of your
messaging protocols (ie: one message to one consumer), then option
2) might well work out better for you, to be honest. Rabbit makes
a lot of trade-offs that focus on flexible messaging topologies
and reliable delivery, all of which can work against raw
throughput, and especially the ability to act as an infinite
buffer.<br>
