RabbitMQ के लचकदार exchanges आणि bindings विविध messaging patterns — work queues, publish/subscribe, routing, topics, आणि request/reply (RPC) — सपोर्ट करतात. RabbitMQ ला विविध कम्युनिकेशन गरजांसाठी वापरण्यासाठी हे पॅटर्न्स समजणे महत्वाचे आहे.
Work queues (task distribution)
WORK QUEUE → distribute tasks among multiple WORKERS (competing consumers):
→ producer → queue → multiple consumers (each message to ONE worker) → parallel processing
→ for: distributing background work; scaling task processing
Publish/Subscribe (broadcast)
PUB/SUB → broadcast a message to MULTIPLE consumers (each gets a copy):
→ FANOUT exchange → every bound queue gets the message → all consumers receive it
→ for: broadcasting events to all interested parties (notifications, updates)
