zetcd is a ZooKeeper 'personality' proxy for etcd that serves the Apache ZooKeeper API backed by an etcd cluster. It lets existing ZooKeeper clients operate on etcd without modification, and includes a cross-checking mode that compares its responses against a real ZooKeeper server for equivalence testing.

Use cases

• migrate applications from zookeeper to etcd without rewriting clients
• run zookeeper client libraries against an etcd cluster
• replace zookeeper servers with etcd in kubernetes environments
• test zookeeper api compatibility against etcd
• avoid running a separate zookeeper ensemble for coordination

When to choose

• you have existing zookeeper clients but want etcd as the backing store
• you want to consolidate coordination services on etcd
• you need to verify zookeeper protocol behavior against etcd via cross-checking

When to avoid

• you are starting fresh and can use etcd's native API directly
• you rely on zookeeper features not emulated by zetcd
• you need a project with frequent releases and active development
