 The `driver` setting defines the driver type to use for Mongo Pumps. It can be one of the following values:

-- `mgo` (default): Uses the mgo driver. This driver is deprecated. This driver supports Mongo versions lower or equal to v4. You can get more information about this driver [here](https://github.com/go-mgo/mgo)
