Message - RabbitMQ - Clustering
- RabbitMQ clustering 就是把物理上的多个 RabbitMQ 的 server instance 组成一个逻辑上的 RabbitMQ server instance.
- Clustering 有效的避免了 hardware failure 导致的系统信息丢失
- all definitions (of exchanges, bindings, users, etc) are mirrored across the entire cluster.
- Queues behave differently, by default residing only on a single node, but optionally being mirrored across several or all nodes. Queues remain visible and reachable from all nodes regardless of where they are located.
