Visoka razpoložljivost v RabbitMQ vključuje grozdenje (več vozlišč) in replicirane vrste čakalnih vrst (zrcaljene ali kvorum vrste čakalnih vrst), tako da sistem preživi napake vozlišč brez izgube sporočil. Razumevanje HA je pomembno za zanesljiv, produkcijski RabbitMQ.
Grozdenje
RabbitMQ CLUSTER → multiple RabbitMQ nodes working together as one logical broker:
→ nodes share metadata (queues, exchanges, bindings, users)
→ distributes connections and load across nodes
⚠️ by default, a queue lives on ONE node → if that node fails, the queue is unavailable
(clustering alone doesn't make queues highly available → need replication)
