Cognite Data Fusion - August 2020 updates

The Cognite Power BI Connector

New function: Time series aggregates

The time series aggregation now accepts a list of IDs instead of a comma separated string. You can now use a column from another query directly as input to the function, making it much easier to use.

Setting the CDF environment for a custom cluster

If a CDF project is on a custom cluster, you can set the CDF Environment to the URL of the API server for the cluster when you connect to CDF.

You can also set a specific API version by appending it to the URL, for example v1. We also support shorthand notations. For example, api/v1 uses the default API endpoint and v1 of the API.

Examples of supported CDF environment values:

• (blank) - uses the default setting (https://api.cognitedata.com)
• api - the same as https://api.cognitedata.com
• api/v1 - the same as https://api.cognitedata.com/v1
• https://api.cognitedata.com
• https://api.cognitedata.com/v1
• xyz - a custom cluster. The same as https://xyz.cognitedata.com
• xyz/v1
• https://xyz.cognitedata.com
• https://xyz.cognitedata.com/v1

New SDK section in the developer portal

The new section gathers the most useful resources and links related to the CDF SDKs:

• Getting started with JavaScript SDK and Python SDK.
• Quick links to reference documentation and GitHub repositories.
• Additional guides such as authentication, upgrade guides for JavaScript SDKs.
• Release notes for SDKs are now part of the developer portal.

Python SDK 2.1

The new release introduces an improved interface to make it easier to work with labels.

To learn more about the changes in new release, see the release notes.

JavaScript SDK 3.0

New major release separates SDK into 3 different packages:

• A core package that contains the SDKs infrastructure. This is used by the other packages and allows users to easily create their own SDK by just defining the interface.
• The stable package contains all the stable API endpoints.
• The beta package extends the stable SDK with beta API functionality.

In addition to structural changes, the new version of the SDK introduces these changes:

• unit attribute is now exposed in data points objects.
• Fields that can have arbitrary string names (Raw, Metadata) are no longer converted to Date objects if their names are: createdTime, lastUpdatedTime, uploadedTime, deletedTime, timestamp, sourceCreatedTime or sourceModifiedTime.

To learn more about the new release, see the release notes.
