RabbitMQ के flexible exchanges और bindings विभिन्न messaging patterns का समर्थन करते हैं — work queues, publish/subscribe, routing, topics, और request/reply (RPC)। इन patterns को समझना विभिन्न communication जरूरतों के लिए RabbitMQ का उपयोग करने की कुंजी है।
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)
