RemoveAttributes activity

A removeAttributes activity removes attributes from a message. For example, given the message that was the result of the addAttributes activity.

{
    "device": {
        "id": "device-123",
        "coord": [ 47.6, -122.3 ]
    },
    "id": "device-123",
    "lat": 47.6,
    "lon": -122.3
}

To normalize that message so that it includes only the required data at the root level, use the following removeAttributes activity.

{
    "removeAttributes": {
        "name": "MyRemoveAttributesActivity",
        "attributes": [
            "device"
        ],
        "next": "MyDatastoreActivity"
    }
}

This results in the following message flowing along the pipeline.

{
    "id": "device-123",
    "lat": 47.6,
    "lon": -122.3
}
