The RabbitMQ feed type in ArcGIS Velocity can subscribe to and consume messages from an externally accessible RabbitMQ broker. For more information about RabbitMQ, see RabbitMQ. RabbitMQ is a message-queueing software that enables distribution and consumption of messages through message queues.
Examples
