Here’s the complete architecture of how Cassandra works:

If outdated data is detected in one of the nodes, Cassandra replicates data from healthy nodes and repairs the damaged ones. Such massively scalable architecture makes it easy to add additional nodes to suit anyone’s needs.Ĭassandra allows communication between nodes and performs fault detection to reveal any damaged nodes in a cluster to prevent the risk of failure. Cassandra works with a peer-to-peer architecture data model, which means that each instance or node is connected to more nodes making up clusters. How Cassandra Database WorksĬassandra aims to enable users to work with high amounts of structured data while preventing any failure that might occur. Additionally, it can perform thousands of write operations in seconds. It mainly focuses on speed, scalability, and performance.Ĭassandra’s data model allows it to retrieve information very quickly.
