Cassandra Practice Test

Cassandra’s architecture is based on a shared-nothing model, which is a key characteristic that differentiates it from many traditional databases. In a shared-nothing architecture, each node in the cluster operates independently without sharing resources with other nodes. This setup enhances scalability and fault tolerance since any node can handle requests independently, and there is no single point of bottleneck or failure.

The shared-nothing approach allows for seamless horizontal scaling; more nodes can be added to the system without major reconfigurations or significant downtime. Thus, as data volume or user load increases, additional nodes can be incorporated to maintain performance and availability.

This design is particularly beneficial in distributed databases like Cassandra, which are designed to handle large amounts of data across multiple servers while ensuring high availability and resilience.
