I'm not sure what you mean by saying "asynchronous RPC".

Take a look at this tutorial:

And feel free to modify the code as you wish.

The usual way of making sure that the consumer isn't swamped
is by using AMQP flow control: `channel.flow` command.

If you want the consumer to slow down, you can reduce
`channel.flow` prefetch to one and introduce a delay before
acknowledging a received message. Though I dont think
the latter is generally a good idea.

We could help more if you explained what you're trying to do.
