surilli opened a new issue #552: Can service-center support highly concurrent service-registry?
URL: https://github.com/apache/servicecomb-service-center/issues/552
 
 
   Firstly, service-center uses Txn interface of etcd clientv3. Etcd limit the max gap between apply and commit index to 5000, and a large number of mutexes may block highly concurrent service-registry requests. For one stress test client sending http request of service-registry continuously to a cluster of three service-center, it hits nearly 17000 TPS but declines rapidly failing to meet our expectation.
   Secondly, the maximum number of service is limited to 50000 and the maximum number of instance is set to 150000. This may limit the capacity for service and instance registry.
