ETCD is a highly available key-value storage system that is used primarily for shared configuration and service discovery. ETCD is developed and maintained by CoreOS and is inspired by ZooKeeper and Doozer, which is written in the go language and handles log replication through the raft consistency algorithm to ensure strong consistency. Raft is a new consistency algorithm from Stanford, suitable for the lo
