The MongoDB Integration Plugin lets you store and retrieve data from your MongoDB Server. Build your own queries select, update and delete data to your database directly from Blueprints. All queries work asynchronously in a separate thread. You can also create new collections and databases.

MongoDB is a cross-platform and open-source document-oriented database, a kind of NoSQL database. As a NoSQL database, MongoDB shuns the relational database’s table-based structure to adapt JSON-like documents that have dynamic schemas which it calls BSON.
This makes data integration for certain types of applications faster and easier. MongoDB is built for scalability, high availability and performance.
