Overview

What is Apache Cassandra?

Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients.

Cassandra keyspaces

A keyspace is the top-level database object that controls the replication for the object it contains at each datacenter in the…
