How Cassandra reads and writes data

Understanding how Cassandra stores data.

To manage and access data in Cassandra, it is important to understand how Cassandra stores data. The hinted handoff feature plus Cassandra conformance and non-conformance to the ACID (atomic, consistent, isolated, durable) database properties are key concepts to understand reads and writes. In Cassandra, consistency refers to how up-to-date and synchronized a row of data is on all of its replicas.

Client utilities and application programming interfaces (APIs) for developing applications for data storage and retrieval are available.
