BigCouch is an open-source, highly available, fault-tolerant, clustered & API-compliant version of Apache CouchDB, which was maintained by Cloudant. On January 5, 2012, Cloudant announced they would contribute the BigCouch horizontal scaling framework into the CouchDB project. The merge was completed in July 2013. Cloudant announced in June 2015 that they were no longer supporting BigCouch.

| - BigCouch is an open-source, highly available, fault-tolerant, clustered & API-compliant version of Apache CouchDB, which was maintained by Cloudant. On January 5, 2012, Cloudant announced they would contribute the BigCouch horizontal scaling framework into the CouchDB project. The merge was completed in July 2013. Cloudant announced in June 2015 that they were no longer supporting BigCouch. BigCouch allows users to create clusters of CouchDBs that are distributed over an arbitrary number of servers. While it appears to the end-user as one CouchDB instance, it is in fact one or more nodes in an elastic cluster, acting in concert to store and retrieve documents, index and serve views, and serve CouchApps. Clusters behave according to concepts outlined in Amazon's Dynamo paper, namely that each node can accept requests, data is placed on partitions based on a consistent hashing algorithm, and quorum protocols are for read/write operations. It relies on Erlang and the Open Telecom Platform, despite using its own RPC mechanism over OTP's own "rex" server. BigCouch was developed to address a common complaint raised by CouchDB skeptics is that "it doesn't scale," by which they mean it does not scale horizontally across many servers. This feature is necessary for CouchDB is to be used to address Big Data problems. (en)
- BigCouch è un database open source compatibile con Apache CouchDB. Assicura alta disponibilità, tolleranza ai guasti e architettura a cluster. In passato era gestito da Cloudant. Il progetto è stato integrato in CouchDB nel luglio 2013. BigCouch permette di creare cluster di CouchDB distribuiti su un numero arbitrario di server. All'utente appare come un'unica istanza di CouchDB, ma in realtà sono uno o più nodi di un cosiddetto "elastic cluster". I nodi collaborano all'unisono per recuperare e memorizzare documenti, indici, viste e far funzionare applicazioni CouchApp. I cluster si comportano secondo i concetti descritti nell'articolo Dynamo di Amazon, in cui ogni nodo può accettare richieste. I dati sono posizionati su partizioni basate su un algoritmo di hashing consistente e protocolli con quorum per le operazioni di lettura/scrittura. È basato su Erlang e , nonostante usi un proprio meccanismo di RPC invece che quello di OTP sul proprio server "rex". BigCouch fu sviluppato per rispondere a una lamentela comune degli scettici di CouchDB: "non è scalabile", nel senso che non è possibile aumentarne la dimensione aumentando il numero di server utilizzati.Questa caratteristica è necessaria a CouchDB per poter essere usato per affrontare problemi relativi ai Big Data.
