Joola supports MongoDB as a Data Store.
MongoDB is an open source, document-oriented database designed with both scalability and developer agility in mind. Instead of storing your data in tables and rows as you would with a relational database, in MongoDB you store JSON-like documents with dynamic schemas.
To use MongoDB with your Joola cluster:
$ npm install joola.datastore-mongodb
In your configuration add the following:
store: mongodb: enabled: true host: localhost
