A Highly Available, Fault-tolerant, Clustered Version of Apache CouchDB

While it appears to the end-user as one Apache CouchDB instance, it is in fact one or more BigCouch nodes in an elastic cluster, acting in concert to store and retrieve documents, index and serve views, and serve CouchApps. BigCouch has been developed and is continually maintained by Cloudant. Clusters behave according to concepts outlined in Amazon’s Dynamo paper, namely that each BigCouch node can accept requests, data is placed on partitions based on a consistent hashing algorithm, and quorum protocols are applied for read/write operations.
