High availability
zookeeper is down
Zookeeper registration center is down, and services exposed by dubbo can also be consumed
- The downtime of the monitoring center will not affect the use, but some sampling data will be lost
- After the database goes down, the registry can still provide service list queries through the cache, but cannot register new services
- Registration center peer-to-peer cluster, after any one goes down, it will automatically switch to another
- After the registry is completely down, service providers and service consumers can still communicate through the local cache
- The service provider is stateless, after any one is down, it will not affect the use
- After the service providers are all down, the service consumer applications will be unavailable and will be reconnected indefinitely for the service provider to recover
