SUMMARY = "A distributed key-value store for shared config and service discovery"
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 \
