Publish/Subscribe with Fanout Exchanges
Learn how to broadcast messages to many consumers at once using RabbitMQ's publish/subscribe pattern built on fanout exchanges and temporary queues.
Beyond a Single Consumer
Work queues deliver each message to one worker. But sometimes every interested consumer needs the same message — like broadcasting a live score to all dashboards.
This is the publish/subscribe pattern.
The Fanout Exchange
Pub/sub in RabbitMQ uses a fanout exchange, which copies every incoming message to all queues bound to it, ignoring routing keys entirely.
