It helps you to accesses information from the server. In the case when there is no response from the connected server, the client automatically redirects the message to another server.Ĭlient: Client is one of the nodes in the distributed application cluster. Server: The server sends an acknowledge when any client connects. ZooKeeper works fast with workloads where reads to the data are more common than writes.It allows you to elect a node as a leader for better coordination.You can increase performance by deploying more machines.It allows to Join/leave node in a cluster and node status at the real time.Computers, which run as a single system which can be locally or geographically connected.It helps to maintain a standard hierarchical namespace similar to files and directories.Helps you to encode the data as per the specific set of rules.

Irrespective o the server that it connects to, a client will be able to see the same view of the service.

The distributed state can be held up, but it’s never wrong It is either given the status of Success or failure.

The transaction process is never completed partially.

It ensures that your application runs consistently.

It allows for mutual exclusion and cooperation between server processes.
