What is the data model of Cassandra?

Cassandra’s data model is based on a distributed, non-relational model. It utilizes a column-based storage structure to store data in a row and column format. In Cassandra, data is organized into a table consisting of a series of rows and columns, where each row represents a data item and each column represents an attribute. This data model helps support large-scale data storage and high-performance read and write operations. Additionally, Cassandra also supports a flexible data model that can dynamically add or remove columns as needed, offering good scalability and fault tolerance.
