Modules configuration

The enrichment modules are configured in a file called default-config.json. This file is included in the JAR and looks like this:

{
  "modules": [
    {
      "className": "com.digitalpebble.spruce.modules.ccf.Storage",
      "config": {
        "hdd_gb_coefficient": 0.65,
        "ssd_gb_coefficient": 1.2
      }
    },
    {
      "className": "com.digitalpebble.spruce.modules.ccf.Networking",
      "config": {
        "network_coefficient": 0.001
      }
    },
    {
      "className": "com.digitalpebble.spruce.modules.boavizta.BoaviztAPIstatic"
    },
    {
      "className": "com.digitalpebble.spruce.modules.ccf.PUE"
    },
    {
      "className": "com.digitalpebble.spruce.modules.electricitymaps.AverageCarbonIntensity"
    },
    {
      "className": "com.digitalpebble.spruce.modules.OperationalEmissions"
    }
  ]
}

This determines which modules are used and in what order but also configures their behaviour. For instance, the default coefficient set for the ccf.Networking module is 0.001 kWh/Gb.

Change the configuration

In order to use a different configuration, for instance to replace a module with an other one, or change their configuration (like the network coefficient above), you simply need to write a json file with your changes and pass it as an argument to the Spark job with '-c'.
