Couchbase Server, originally known as Membase, is an open source, distributed (shared-nothing architecture) NoSQL document-oriented database that is optimized for interactive applications.

Couchbase Server, originally known as Membase, is an open source, distributed (shared-nothing architecture) NoSQL document-oriented database that is optimized for interactive applications. These applications must service many concurrent users; creating, storing, retrieving, aggregating, manipulating and presenting data. In support of these kinds of application needs, Couchbase is designed to provide easy-to-scale key-value or document access with consistent low latency and high sustained throughput. It is designed to be clustered from a single machine to very large scale deployments, with no application code changes to facilitate that.
