I've used AMQP for a couple of years now but never used Pika in production. Recently I've been using Haigha in my AMQP Dispatcher project but needed a client for Tornado, which Pika supports. There is an example in the Pika docs of using the Tornado Connection but it doesn't provide as usable an interface as I'd like.

I wrote an client for internal use that handles the conditions I needed by default (including callbacks with the result of RabbitMQ publish confirmations) and after talking with a previous coworker put it into a gist.

It doesn't handle some things (like publish a content type with the encoded json) and could have some better names but it may be of use to more people.
