About writes

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

Cassandra includes client utilities and application programming interfaces (APIs) for developing applications for data storage and retrieval.
