RabbitMQ

RabbitMQ is a light-weight and easy to use message broker that we will use to exchange JSON messages between services.

1. Introduction A quick introduction to RabbitMQ message queues.
2. NLTK A pipeline of NLTK services
3. Broadcast An example of how to blast a message to all listeners.

Notes

1. RabbitMQ sends messages as byte arrays. These examples assume the byte arrays are UTF-8 strings, but they could be images or video or any other datatype.
2. There is no Right Way^TM to design and build an application using message queues. There may be some design patterns to follow, but RabbitMQ is simply a toolkit for sending messages between processes. What those messages mean and how they are interpreted is up to the producers and consumer of the messages to determine.
