Description

Introduction

Apache Cassandra is a highly scalable and distributed NoSQL database designed to handle large amounts of data across multiple servers with no single point of failure. Known for its high availability and fault tolerance, Cassandra is widely used for applications requiring real-time data access, high write throughput, and seamless scalability. It supports a wide range of use cases, including analytics, operational workloads, and Internet of Things (IoT) applications, making it a robust choice for enterprises with demanding data requirements.

Prerequisites

• Basic understanding of database concepts and data modeling.
• Familiarity with distributed systems and replication principles.
• Knowledge of Java or Python for interacting with Cassandra APIs.
• Access to a development environment for hands-on practice with Cassandra.
