Apache Cassandra

Apache Cassandra is a highly scalable, distributed NoSQL database designed to handle large amounts of data across many commodity servers without any single point of failure. It is well-suited for handling high-velocity, high-volume transactional data, making it popular for real-time applications, IoT, and big data processing.

Whether you’re new to NoSQL databases or already have experience with relational databases, this page will guide you through the fundamentals of Cassandra, from installation and configuration to advanced topics like clustering, performance tuning, and data modeling.

What You’ll Find Here:

• Introduction to Apache Cassandra: Learn what Apache Cassandra is, its architecture, and the types of use cases where it excels compared to other databases.
• Cassandra Architecture: Understand how Cassandra’s distributed architecture works, including its use of nodes, data centers, and clusters for high availability and scalability.
• Installing Cassandra: Learn how to install Cassandra on different operating systems (Linux, macOS, Windows) and configure it for optimal performance.
• Cassandra Data Model: Discover Cassandra’s unique data model, including tables, rows, and columns, and how it differs from relational databases.
• Creating Keyspaces and Tables: Learn how to create and manage keyspaces (databases) and tables in Cassandra, and define the primary key structure for efficient data access.
• Cassandra Query Language (CQL): Explore Cassandra Query Language (CQL), a SQL-like query language used to interact with Cassandra databases, and learn how to perform CRUD (Create, Read, Update, Delete) operations.
• Data Distribution & Replication: Understand how Cassandra distributes data across nodes and how replication works to ensure high availability and fault tolerance.
• Consistency Levels in Cassandra: Learn about Cassandra’s consistency model and how to configure consistency levels to strike the right balance between performance and reliability.

• Security in Cassandra: Explore security best practices for Cassandra, including authentication, authorization, and encryption to protect your data.
• Monitoring Cassandra: Learn how to monitor Cassandra’s performance using built-in tools like Nodetool and third-party monitoring solutions to identify and resolve issues.
• Cassandra vs. Other NoSQL Databases: Compare Cassandra with other NoSQL databases like MongoDB, Couchbase, and HBase to understand when to choose Cassandra for your application.
• Use Cases for Apache Cassandra: Explore real-world use cases where Cassandra excels, including real-time analytics, IoT applications, time-series data, and large-scale transactional systems.
• Integrating Cassandra with Other Technologies: Learn how to integrate Cassandra with other technologies, such as Apache Spark, Kafka, and Hadoop, to create a complete big data ecosystem.

Whether you’re developing applications that require high availability, handling massive amounts of data, or building systems that need to scale seamlessly, Apache Cassandra can help you achieve those goals. This page will provide the foundational knowledge and advanced strategies you need to work with Cassandra effectively.
