Managing Data¶

To manage data, you need to understand how Cassandra writes data, eventually tuning data consistency, and then compacts and stores data on disk. Atomicity, consistency, isolation, and durability of data is described in this section. You can access and manage data in Cassandra using a utility, such as the Cassandra Command Line Interface (CLI) and the Cassandra Query Language (CQL). Application programming interfaces (APIs) can be used for developing applications that use Cassandra for data storage and retrieval.
