zetcd: running ZooKeeper apps without ZooKeeper

By ris The CoreOS Blog introduces the first
beta release, v0.0.1, of zetcd. “Distributed systems commonly rely
on a distributed consensus to coordinate work. Usually the systems
providing distributed consensus guarantee information is delivered in order
and never suffer split-brain conflicts. The usefulness, but rich design
space, of such systems is evident by the proliferation of implementations;
projects such as chubby, ZooKeeper, etcd, and consul, despite differing in philosophy
and protocol, all focus on serving similar basic key-value primitives for
distributed consensus. As part of making etcd the most appealing foundation
for distributed systems, the etcd team developed a new proxy, zetcd, to
serve ZooKeeper requests with an unmodified etcd cluster.
