Questions tagged [rabbitmq]
RabbitMQ is an open-source message broker originally implementing the AMQP protocol with additional messaging protocols supported via a plug-in architecture. This tag should be used with questions involving the RabbitMQ server message broker product or questions concerning the source code and implementation of the RabbitMQ product. A specific protocol tag such as amqp or mqtt may also be appropriate as well as the OS and programming language being used.
