Apache Zookeeper Features

So, here is the list of best Features of ZooKeeper:

i. Naming service

To every node, identifying ZooKeeper attaches a unique identification which is quite similar to the DNA. So, that helps to identify it.

ii. Updating the node’s status

Also, it has the flexibility of updating every node. Hence, that feature permits it to store updated information about each node across the cluster.

iii. Managing the cluster

Moreover, in Zookeeper, the status of each node is maintained in real-time. That leaves lesser chances for errors as well as ambiguity, that’s how it manages the cluster.

iv. Automatic failure recovery

While modifying, ZooKeeper locks the data, so, if a failure occurs in the database, that helps the cluster to recover it automatically.

v. Simplicity

By using a shared hierarchical namespace, it coordinates.

vi. Reliability

When one or more nodes fail, the system keeps performing.

vii. Ordered

By stamping each update, it keeps track with a number denoting its order.

viii. Speed
