Theres a rabbit on my symfony

The document discusses integrating RabbitMQ with Symfony2 to enable asynchronous messaging capabilities. It describes how RabbitMQ and the AMQP protocol allow for decoupling of components through message passing. Examples are provided of using RabbitMQ for batch processing and image uploading tasks in Symfony2, including code for a publisher and consumer.
