RabbitMQ's flexible Exchanges und Bindings unterstützen verschiedene Messaging-Muster — Work Queues, Publish/Subscribe, Routing, Topics und Request/Reply (RPC). Das Verständnis dieser Muster ist entscheidend für die Nutzung von RabbitMQ für unterschiedliche Kommunikationsanforderungen.
Work Queues (Task-Verteilung)
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)
