Apache Curator

Apache Curator will help developers working on projects running ZooKeeper get a basic package of widely used plugins and components in one single archive.

These components can be used to enhance default ZooKeeper capabilities and target a broader spectrum of features with their software.

Apache ZooKeeper is an open source centralized distribution server where information and configurations about distributed applications can be managed.
