What is an Active Everywhere Masterless Database Architecture?

DataStax Enterprise (DSE) is the Active Everywhere Database built on Apache Cassandra’s masterless architecture, where multiple servers (or nodes) are grouped together in a cluster. With DSE, scaling is truly effortless and highly predictable. In fact, it’s linear. If you want to double the performance of your cluster, you simply double the number of nodes in the cluster. That’s it! And you can do this infinitely. Moreover, as these systems scale, you can have the data closer to the application within any region in the world. This cuts down data transfer costs and increases performance by reducing latency. In master-slave and multi-master models, this is very hard to do and comes with performance penalties, but with DSE, it is easily and automatically configured.
