Cassandra operates its read and write operations through a distributed architecture. It utilizes a data model known as a distributed hash table to store data, distributing it across multiple nodes where each node is responsible for storing a portion of the data.<\/p>\n

When performing a write operation, the client sends data to one node in the Cassandra cluster. This node is responsible for writing the data to the corresponding partition and propagating it to other nodes to ensure data replication and fault tolerance. Cassandra utilizes a mechanism called hinted handoff to guarantee data consistency.<\/p>\n

When conducting a read operation, the client sends a read request to one node in the Cassandra cluster. This node determines the location of the data storage based on the partition key and retrieves the data from the corresponding node. If replicas of the data are needed, Cassandra will also retrieve data from other nodes and return it to the client.<\/p>\n

Overall, Cassandra achieves high availability and data consistency through its distributed architecture and data replication mechanism. Additionally, Cassandra supports various levels of read and write consistency, allowing users to choose the most suitable level based on their needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
