FYI https://coreos.com/blog/etcd3-a-new-etcd.html
I think the ZooKeeper team needs to have a formal answer for etcd/consul. The developer community keeps asking questions like “compare it to ZK” and the etcd devs are very public and active with their responses. E.g. https://news.ycombinator.com/item?id=12011066 -Jordan P.S. This gives a chance to plug my TTL PR which is a feature they have that ZK doesn’t: https://issues.apache.org/jira/browse/ZOOKEEPER-2169
