With a key/value design that delivers powerful – yet simple – data models for storing massive amounts of unstructured data, Riak KV is built to handle a variety of challenges facing Big Data applications that include tracking user or session information, storing connected device data and replicating data across the globe.
Riak KV automates data distribution across the cluster to achieve fast performance and robust business continuity with a masterless architecture that ensures high availability, and scales near linearly using commodity hardware so you can easily add capacity without a large operational burden.
