Big Data with Apache Cassandra focuses on managing and processing large-scale, high-velocity data across distributed systems. Cassandra is designed for high availability, fault tolerance, and horizontal scalability without single points of failure. This training explains how to design data models, manage clusters, and optimize queries for big data applications. It also covers partitioning, replication strategies, consistency levels, and performance tuning techniques. You will learn how organizations use Cassandra for real-time analytics, IoT data, messaging systems, and large-scale web applications. The course also highlights best practices for building scalable and resilient distributed databases.
