via Offloads

Sentiance provides data offloads with driving insights to the clients on a daily basis.

What are Offloads

The Sentiance platform offers various methods to access and analyze your end-users' data, one of which is through offloads—our implementation of a file-based system, typically in CSV format. Offloads generally contain data for all your users over a specific timeframe, by default a 24-hour tumbling window. Detailed field descriptions can be found below.

While offloads contain much of the core data, they do not include certain elements such as predictions, coaching data, or some fine-grained details.

Please consult with your Sentiance contact person to discuss the offloads before implementing.

Accessing Offloads

Access to offloads is managed by the Sentiance Cloud API, with permissions authorized by the API Key Scopes (OFFLOADS_READ and OFFLOADS_GENERATE_URL).

To check available offloads, use an API Key with the OFFLOADS_READ scope. The query example is:

query {
  offloads(from: "2023-06-04", to: "2023-06-04") {
    day
    type
    files {
      format
      link {
        expires_at
        url
      }
      name
      size
    }
  }
}

from and to are always days in the format YYYY-MM-DD. The response looks like the following.

{
  "data": {
    "offloads": [
      {
        "day": "2023-06-04",
        "files": [
          { "format": "csv.gz", "link": null, "name": "transports", "size": 20434 }
        ],
        "type": "OFFLOAD_TYPE_TRANSPORTS"
      },
      {
        "day": "2023-06-04",
        "files": [
          { "format": "csv.gz", "link": null, "name": "driving_events_all", "size": 277423 }
        ],
        "type": "OFFLOAD_TYPE_DRIVING_EVENTS_ALL"
      },
      {
        "day": "2023-06-04",
        "files": [
          { "format": "csv.gz", "link": null, "name": "driving_events_significant", "size": 61428 }
        ],
        "type": "OFFLOAD_TYPE_DRIVING_EVENTS_SIGNIFICANT"
      },
      {
        "day": "2023-06-04",
        "files": [
          { "format": "csv.gz", "link": null, "name": "trajectories", "size": 850284 }
        ],
        "type": "OFFLOAD_TYPE_TRAJECTORIES"
      }
    ]
  }
}

Offloads of several types are available (based on which Sentiance product offering you are using). Each day will contain one offload of each type and each offload item may have one or more associated files to download.

The files list their format, name, size and a link to download that file.

In the response above the link field is null since no links have been generated for these files yet. Link generation is done with an API Key with the scope OFFLOADS_GENERATE_URL.

mutation {
  generate_offload_url(day: "2023-06-04", offload_type: OFFLOAD_TYPE_TRANSPORTS) {
    offload {
      day
      type
      files {
        format
        link {
          expires_at
          url
        }
        name
        size
      }
    }
  }
}

To generate a link to the offload files, you must use the generate_offload_url mutation, giving the day of the offload and the type as input. This will respond with.

{
  "data": {
    "generate_offload_url": {
      "offload": {
        "day": "2023-06-04",
        "files": [
          {
            "format": "csv.gz",
            "link": {
              "expires_at": "2023-06-27T11:32:29Z",
              "url": "https://sentiance-g2-driving-offloads.s3.eu-west-1.amazonaws.com/00000000000000000000000a/2023-06-04_0/transports.csv.gz?..."
            },
            "name": "transports",
            "size": 20434
          }
        ],
        "type": "OFFLOAD_TYPE_TRANSPORTS"
      }
    }
  }
}

Links expire after a set time and must be regenerated if needed. Offloads for the previous day are fully available, while current-day offloads may be incomplete.
