如果单元集群部署在异地,所形成的『融合集群』,就是全球容灾集群:
- 客户端引入 unitName 字段,默认情况,不同unitName获取的都是单元集群的元数据
- 灾难发生时,允许读其它 单元集群 未消费完的数据
-- 顺序性,Consumer端按照队列消费,天然是顺序的;只要可以针对Producer端固定队列数量就可以实现顺序
-- 单元内读写,跨单元可读,就可以实现『单元内保序』
+- 顺序性的关键在于 固定Producer端可见的队列
+- Consumer 端按照队列消费,天然是顺序的
+- 单元内读写,跨单元可读,就可以实现『单元内保序且具备容灾能力』
- 跨单元读,是指读『其它clusterName』的队列,不一定是远程读,如果本单元有相应的Slave节点,则直接本地读
