This app provides Barrel Hosting service.
Started as fork of Apache CouchDB 1.3.0, Barrel is an effort to maintain the CouchDB HTTP API along with high performance and modern features such as the view changes based replication, full Erlang OTP support, a revised storage and P2P distribution.
Since it shares the same HTTP API, you can port any existing CouchDB application to Barrel just with a replication only. Then you can progressively enhance it and take advantage of Barrel unique features. Similarly it is possible to build apps which gracefully degrade using the CouchDB official API only.
