To enable support for queues on a database, in your settings.<env>.json file add the "queues": true flag to a database config object:


  "config": {
    "databases": [
        "provider": "mongodb",
        "queues": true,
        "options": {}
  "global": {},
  "public": {},
  "private": {}

Once added, any queue defined in the app will automatically have its jobs routed to the specified database. If a queue is not defined as external in the app, the app will also read jobs from the specified database and run them internally.
