Simplified query language interface for Apache CouchDB, inspired by MongoDB, and made available on Cloudant service first, and then on Apache CouchDB 2.0.

"Mango" is a MongoDB inspired query language interface for Apache CouchDB. It is designed to provide users a more natural conversion to Apache CouchDB.

It is worth noting that it enables the creation of indexes (a.k.a. 'views'), without having to implement explicitly a map and a reduce functions.

The endpoint added is for the HTTP-URI pattern /dbname/_query and has the following characteristics:

  • the only HTTP method supported is POST,
  • the request Content-Type must be application/json,
  • the response is a single JSON object or array that matches to the single command or list of commands that exist in the request.
