Spring boot + Cassandra CRUD example.

Introduction:

Apache Cassandra is an open-source, distributed, NoSQL database management system designed to handle large amounts of data across many commodity servers. It provides high availability with no single point of failure. Spring Boot is an open-source framework that provides a quick and easy way to create robust and production-ready applications. In this article, we will explore how to use Spring Boot with Cassandra DB to perform CRUD operations.

Setting up the Cassandra database:

Before we start with the development, we need to set up the Cassandra database. Here are the steps to set up the Cassandra database:

1. Download and install the Cassandra database on your machine.
2. Start the Cassandra service by running the command ./bin/cassandra from the Cassandra installation directory.
3. Connect to the Cassandra database by running the command ./bin/cqlsh from the Cassandra installation directory.

Creating a Spring Boot project:

To create a new Spring Boot project, follow these steps:

1. Open the Spring Initializr website (https://start.spring.io/).
