Feature Description
The ETCD client implements the following components:
-
Balancer that establishes the gRPC connections to an ETCD cluster.
-
API client that sends RPCs to an ETCD server.
-
Error handler that decides whether to retry a failed request or switch endpoints.
The App-infra-based pods using memory cache in 5G communicate with the ETCD server. This communication is to store their critical data on a distributed system through the ETCD client load balancer. The memory cache uses the ETCD client 3.3 version, which implements the clientv3-grpc1.7 library.
