Cassandra

Apache Cassandra is an open-source, distributed NoSQL database management system designed to handle large amounts of data across multiple servers with high availability and no single point of failure. It is commonly used for scalable, fault-tolerant, and high-performance database workloads.

Version: Apache Cassandra 5.0.8

The solution supports common database workflows including distributed data storage, high availability, replication, fault tolerance, and fast read/write operations. It is ideal for cloud-native applications, analytics platforms, IoT workloads, messaging systems, and large-scale enterprise applications.

Features of Apache Cassandra:

• Distributed NoSQL database for large-scale data storage.
• High availability with no single point of failure.
• Supports replication across multiple nodes and data centers.
• Uses Cassandra Query Language (CQL) for database operations.
• Designed for high write throughput and horizontal scalability.
• Includes CLI tools such as cqlsh and nodetool for database management.
