Releases

This article documents the ongoing improvements we're making to the Cognite Power BI connector.

August, 2023​

Added

  • Connect Microsoft Power BI to CDF Data Modeling using the Data Modeling OData gateway

November, 2021​

Added

  • We normalize the tenantId value for Azure AD authentication to allow tenantId, tenantID, or tenantid.

Bug fixes

  • The connector now uses the CDF environment over the project URL as the Azure AD resource to get a token for the correct URL if both are set.

  • For custom queries with OIDC sign-in, the query URL requires a valid token. The connector now sends the auth challenge (empty bearer token) to the service URL, not the query URL.

  • We now disable the TimeseriesAggregate function for custom queries on the /Events endpoint to not interfere with custom queries.

  • For the TimeseriesAggregate function, the connector now escapes special characters in tags before sending them to the OData API.

June, 2021​

This release contains a bug fix for the TimeseriesAggregate function. The list of tags is now escaped using Uri.EscapeDataString, which fixes a problem if any of the tags has any special characters.

December, 2020​

From Beta to Version 1

The Cognite Power BI connector moves from Beta to Version 1. The new version is backward-compatible, and you can update the connector without migrating your dashboards. If you have manually installed an earlier version of the plugin, remove it by deleting it from Documents\Power BI Desktop\Custom Connectors.

Improved support for time series data

The Cognite Power BI connector V1 has improved processing time for time series data and removes the limitations on the number of time series you can download. For example, you can download thousands of time series, each with data from 1 year and with 1 day granularity.

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
