Today, in this ZooKeeper tutorial, we will see ZooKeeper Features. One distributed application offers a lot of applications, but these applications also come with difficulties as well. Though, these difficulties are very hard to address.

So, to overcome all these complexities, Apache ZooKeeper provides a wide range of good features of Zookeeper to the user. Hence in this Zookeeper article, here we will learn best Zookeeper Features to understand What makes it stand out from the crowd so well.

So, let’s start exploring ZooKeeper Features

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

In the cases where ‘Reads’ are more common, it runs with the ratio of 10:1.

ix. Scalability

Performance of Zookeeper can be enhanced by deploying more machines.

x. How is the order beneficial?

To implement higher-level abstractions order is required.

xi. ZooKeeper is fast

Zookeeper works very Fast in “read-dominant” workloads.

xii. Ordered Messages

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

xiii. Serialization

Serialization means a surety about the consistency of running application. Though, this approach can be used in MapReduce for coordination of queue in order to execute running threads.

xiv. Reliability

As soon as it applies the update until a client overwrites the update, it will persist from that time forward.

xv. Atomicity

Either data transfer succeeds or fails completely.

xvi. Sequential Consistency

Sequential Consistency means, in the same order that they were sent, they apply the updates from a client, in that order only.

xvii. Single System Image

Despite the server from which it connects to, a client will see the same view of the service.

xviii. Timeliness

In some definite time amount, system’s client’s view is up-to-date.
So, this was all in Apache ZooKeeper Features. Hope you like our explanation.

Conclusion

Hence, in this ZooKeeper tutorial, we have seen all the best features of Zookeeper that make it stand out from the crowd. Next, we will see ZooKeeper Architecture. Still, if any doubt regarding Apache ZooKeeper features, ask in the comment tab.
