[GitHub] [shardingsphere] chenjia123 opened a new issue #11470: Why is the NACOS config center implemented but no registry?
chenjia123 opened a new issue #11470:
URL: https://github.com/apache/shardingsphere/issues/11470
## Env: Sharding-proxy 4.1.1
## Aim: Try using nacos instead of ZK
I use the following configuration file:
```yaml
# server.yaml
orchestration:
orchestration_ds:
orchestrationType: registry_center,config_center,distributed_lock_manager
instanceType: nacos
serverLists: http://localhost:8848
namespace: orchestration
```
However, it does not take effect and has an exception:
```
Exception in thread "main" java.lang.RuntimeException: Invalid `org.apache.shardingsphere.orchestration.center.RegistryCenterRepository` SPI type `nacos`.
at org.apache.shardingsphere.spi.TypeBasedSPIServiceLoader.newService(TypeBasedSPIServiceLoader.java:46)
at org.apache.shardingsphere.orchestration.core.registrycenter.RegistryCenterRepositoryServiceLoader.load(RegistryCenterRepositoryServiceLoader.java:49)
at org.apache.shardingsphere.orchestration.core.facade.ShardingOrchestrationFacade.<init>(ShardingOrchestrationFacade.java:69)
at org.apache.shardingsphere.shardingproxy.Bootstrap.startWithRegistryCenter(Bootstrap.java:131)
at org.apache.shardingsphere.shardingproxy.Bootstrap.main(Bootstrap.java:87)
```
And then I found this:
So,
- Why is this project(sharding-orchestration-center-nacos) incomplete? The RegistryCenterRepository interface is not implemented.
- Isn't NACOS suitable for the registry?
- Why do we need a registry in a sharding-proxy? In some instances,I think just need the config center.
Thanks!

Reg center need to ephemeral or TTL, only ZooKeeper and etcd can support the feature.
So NACOS has been removed from version 5.x.
