devel/etcd3/pkg-descr

+A highly-available key value store for shared
+configuration and service discovery. etcd is
+inspired by zookeeper and doozer, with a focus on:
+
+* Simple: curl'able user facing API (HTTP+JSON)
+* Secure: optional SSL client cert authentication
+* Fast: benchmarked 1000s of writes/s per instance
+* Reliable: Properly distributed using Raft
+
+Etcd is written in Go and uses the raft consensus
+algorithm to manage a highly-available replicated log.
