The main usage of the data model is to maintain synchronization in the zookeeper cluster and explain the metadata of each Znode. config namespace is used for centralized configuration and the workers namespace is used for naming process. Considering that as a root, you have two more namespaces underlying the root. In the below diagram, you can see the Znode separated by a ‘/’. Next, in this zookeeper tutorial article, we will learn the Data model of Zookeeper.Ī Zookeeper Data Model follows a hierarchical namespace where each node is called a Znode, a part of the system where the cluster functions. In case if the server fails to respond, then they automatically redirect themselves to the next available server Similar to servers, the client also sends signals to servers regarding their availability. Its duty is to follow the orders passed by the Leader.Ĭlients are the nodes that request service from the server. It has access to recover the data from any of the failed nodes and performs automatic data recovery for clients.Ī follower is one of the servers in the Ensemble. It sends its alive status to its client in order to inform its clients about its availability.Įnsemble Leader is elected at the service startup. It is one among-st the other servers present in the Zookeeper Ensemble whose objective is to provide all sorts of services to its clients. The Ensemble requires a minimum of three nodes to get itself set up. It is basically the collection of all the Server nodes in the Zookeeper ecosystem. The Architecture of Apache Zookeeper is categorized into 5 different components as follows: Participants in the Zookeeper architecture can be enlisted as follows. It is essentially designed for providing service for distributed systems offering a hierarchical key-value store, which is used to provide a distributed configuration service , synchronization service, and naming registry for large distributed systemsĪpache Zookeeper basically follows the Client-Server Architecture. Zookeeper is a cluster coordinating, cross-platform software service provided by the Apache Foundation. Zookeeper solves the management of the distributed environment by its simple architecture and personalized API. Apache Zookeeperis one of the top-notch cluster coordination services that use the most robust synchronization techniques in order to keep the nodes perfectly connected. ![]()
