%description
etcd is a distributed reliable key-value store for the most critical data of
a distributed system, with a focus on being:

  * Simple: well-defined, user-facing API (gRPC)
  * Secure: automatic TLS with optional client cert authentication
  * Fast: benchmarked 10,000 writes/sec
  * Reliable: properly distributed using Raft

etcd is written in Go and uses the Raft consensus algorithm to manage
a highly-available replicated log.
