Default

Sets default values for frame attributes that don't have existing values.

This layer is usually used at the beginning or at the end of a Layered Frame Analytic to fill in any default values for attributes that couldn't be captured.

For example, you might choose to set a value to '0' if it couldn't be calculated.

Because key values are required for the capture to be added to the database, this layer is most often used to ensure all keys have valid values.

If the frame contains the following attributes…

{
   "type": "default",
   "values": ["Max Temperature","Max Vibration"],
   "value": 0
}

Your final frame would contain the following values…

Note that the existing value for temperature isn't changed.
