Wide-Column Store

A NoSQL database that organizes data into rows with dynamic columns grouped into column families, built for massive write throughput.

Definition

Wide-column stores such as Apache Cassandra, HBase, Google Cloud Bigtable and the Cosmos DB for Apache Cassandra API spread data across clusters by row or partition key. They excel at time-series, IoT and high-volume event data, with queries designed around the key.

Exam tip

On Google Cloud, high-throughput, low-latency time-series or IoT data at petabyte scale points to Bigtable.
