Let us first understand what a NoSQL database does.A NoSQL database (sometimes called as Not Only SQL) is a database that provides a mechanism to store and retrieve data other than the tabular relations used in relational databases. Apache Cassandra is a highly scalable, high-performance distributed database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Class Summary Cassandra is a distributed database management system designed for handling a high volume of structured data across commodity servers. The tutorial starts off with a basic introduction of Cassandra followed by its architecture, installation, and important classes and interfaces. It provides highly available service with no single point of failure.Listed below are some of the notable points of Apache Cassandra −.It is scalable, fault-tolerant, and consistent.Its distribution design is based on Amazon’s Dynamo and its data model on Google’s Bigtable.Created at Facebook, it differs sharply from relational database management systems.Cassandra implements a Dynamo-style replication model with no single point of failure, but adds a more powerful “column family” data model.Cassandra is being used by some of the biggest companies such as Facebook, Twitter, Cisco, Rackspace, ebay, Twitter, Netflix, and more.Cassandra has become so popular because of its outstanding technical features. The tutorial also has dedicated chapters to explain the data types and collections available in CQL and how to make use of user-defined data types.This tutorial will be extremely useful for software professionals in particular who aspire to learn the ropes of Cassandra and implement it in practice.It is an elementary tutorial and you can easily understand the concepts explained here with a basic knowledge of Java programming. However, it will help if you have some prior exposure to database concepts and any of the Linux flavors. Cassandra collections are a good way for handling tasks. It provides high availability with no single point of failure.The tutorial starts off with a basic introduction of Cassandra followed by its architecture, installation, and important classes and interfaces. The outermost container is known as the Cluster. NoSQL databases are sometimes called Not Only.Here are the differences between relation databases and NoSQL databases in a tabular format.There are following features that Cassandra provides.Cassandra is a non-relational database that can be used for different types of applications.

In this tutorial, you will see the various concept Cassandra Tutorial for Beginners: Learn in 3 Days
For failure handling, every node contains a replica, and in case of a failure, the replica takes charge. It is a type of NoSQL database. It uses a column-based storage model to capture large amounts of unstructured data. Our Cassandra tutorial is designed for beginners and professionals both. Cassandra database is distributed over several machines that operate together. Cassandra data structures are faster than relational database structures.NoSQL databases are increasingly used in Big Data and real-time web applications. Thereafter, it proceeds to cover how to perform operations such as create, alter, update, and delete on keyspaces, tables, and indexes using CQLSH as well as Java API. Cassandra is a distributed database management system designed for handling a high volume of structured data across commodity servers.Cassandra handles the huge amount of data with its distributed architecture. It makes some operations faster in NoSQL.
Apache Cassandra is a well-established wide-column NoSQL database. It is provided by Apache.
NoSQL databases store and retrieve data other than tabular relations such as relation databases.NoSQL databases include MongoDB, HBase, and Cassandra.There are following properties of NoSQL databases.Data structures used in Cassandra are more specified than data structures used in relational databases.
