ZooKeeper is a distributed, open-source coordination service for distributed applications. It exposes a simple set of primitives that distributed applications can build upon to implement higher level services for synchronization, configuration maintenance, and groups and naming. It is designed to be easy to program to, and uses a data model styled after the familiar directory tree structure of file systems.
It runs in Java and has bindings for both Java and C.
Behaim’s know-how covers Zookeper’s setup, configuration, production deployment and the implementation of client applications which make use of Zookeeper’s API.
