ZK vs ETCD

Quick notes about implementation difference between ZK and ETCD not Paxos vs Raft

Zookeeper

PRO:

• Industry battle tested, it is the most widely used concensus algorithm implementation

• Stateful connection to ZK quorum (implies more tight and strong concensus)

Ungit: The easiest way to use git.

---

I love Git, I think it is better than the invention of slice of bread. Git is a version control system that is elegantly distributed yet beautifully fault tolerant with powerful features. Git is a fundamental development tool that powers my company, GoGuardian, and many other companies and communities. But just like anything in our lives, it is not perfect. It has its own dark side. Git is notorious for having sharp learning curve and complex commands. If you think learning git or explaining git is easy, good for you. You are a better person than I will ever be so go cure cancer. But for most of us peons, git is a challenging beast to wrap our heads around especially for more complex operations. It may possibly be due to the fact that our minds have been abused and in the shape of CVS, SVN or, even worse, clearcase. But I'm not the only one to think this: exhib
