Hi Community,Has anyone successfully configured the Cognite DB Extractor to connect to Databricks via ODBC using a service principal?I was able to connect to Databricks using a Personal Access Token (PAT), but I am experiencing issues when trying to authenticate with a service principal.Any guidance or examples would be greatly appreciated.Thanks in advance,Andre

We are migrating to the core data model. Time series we tested. We can ingest CogniteTimeSeries directly from the OPC-UA extractor. Assets are in progress.Sequences are our open question. We use them heavily for three things:Multi-dimensional rows tied to a timestamp or time range, where one time series per dimension is the wrong shape. Static reference data that many Functions read. Schemas where one data modelling instance per row would explode our instance count — short heating episodes, small production batches, and similar.What makes them attractive is the combination: readable in the UI, integer indexing, cheap, fast, and metadata slots both per column and per sequence.Looking at the core data model reference, I see no sequence concept — CogniteTimeSeries, CogniteActivity, CogniteFile and so on are all there, but nothing for tabular data. We have noted CogniteTimeSeries with type: state and CogniteStateSet, which covers state classification, but not the multi-column case.So:Is a

Hi Team,We are currently exploring migration of our existing content to use Flexible Data Modeling in CDF, and we are facing some challenges while configuring the OPC UA Extractor.At the moment, we are still pointing the extractor to the traditional Asset-Centric Time Series (dataset-based approach) and then transforming the data into our Data Model types afterward. However, we would like to ingest data directly into a view that implements the CogniteTimeSeries type.We would appreciate your guidance on the following: Do you have any example .yml configuration for the OPC UA Extractor that ingests data directly into a view implementing CogniteTimeSeries? Are there any best practices or recommended approaches for this setup? Is the following documentation the correct reference for this use case?https://docs.cognite.com/cdf/integration/guides/extraction/configuration/opcua#data-models Additionally, we are also evaluating OPC Events ingestion: Should OPC Events be modeled using Cognite

I have exactly the same issue that in Cognite Hub, somebody solved it and said: “I’ve revoked your MFA so you will have to re-register it for our Hub tenant” could you please helping me revoking the MFA and please explaining me how to re-register? thanks.

Hi Team,We are working as a data platform team and there are multiple data product teams using our application. Each data product team has a different space to isolate their data. Is there a possibility to see the storage statistics restricted to space level? Clients also want to see “max number of concurrent requests”.

Hi everyone,I'm currently taking the "Introduction to CDF & Grafana" course on the Academy, but I've hit a roadblock due to a mismatch between the tutorial videos and the current UI. It looks like the Grafana UI and the underlying Cognite plugin have changed significantly since the course videos were recorded, and I'm stuck trying to plot my data.Here is a breakdown of my current setup and where I am getting blocked:Current Setup & Connection Course Reference: Introduction to CDF & Grafana (specifically the hands-on video tutorials for dashboard creation). Connection Status: The connection to the CDF database (cognitedata-datasource) is active and successfully authenticated. The IssueThe updated UI dropdowns now primarily expose modern Data Modeling spaces (such as CogniteTimeSeries (cdf_cdm) v1, CogniteExtractorTimeSeries, etc.).Because the UI seems locked into searching within these specific, unmapped modeling spaces, I cannot retrieve my classic data: I've tried search

Hi experts, In order to decide whether to use an aggregation strategy (or no aggregation at all), I need to know the number of data points between two timestamps without aggregation (server-side calculation). I’m looking for this code of call :client.time_series.data.count(external_id=<str>, start=<int | datetime>, end=<int | datetime>) -> intI'm trying to avoid having to perform a granularity calculation Thanks !Regards,Pierre

We have an issue in our production system that influence many users. We have a app using JavaScript SDK where requests to the Group API times out.  Can you please trace one of the request timing out: 492e1fee-234e-95eb-b371-8a11870708e8 

On a user.Group.yaml file we are able to set specific ids to certain capabilities, such as datasets:  - datasetsAcl: actions: - READ scope: idScope: ids: - datasetId1 - datasetId2 Are we able to also do this for agents via agentsAcl run? I couldn’t find anything specifying it in the documentation and the assistant claimed it was not possible. I wanted to double check here if someone knew more about this.

I have 4 views that implement CogniteAsset. When clicking on an instance and heading over to the properties tab, there are four properties there:Asset class Name Asset class Description Asset class External Id Asset class SpaceThese are visible for 3 of the 4 views. Looking at the propertyLayout, I did not see any reference to an asset class in a view where they are visible, and neither in a view where they are hidden. I’ve tried adding the following to the PropertyLayout section of views where they are visible in the UI:- property: assetClass  hidden: true But it did not help. What is the factor that determine whether these are visible or not?

Hi, Currently been working on the deployment of an app through Flows, and during my first deployment + activation, it went well. The issue was that the name and description I had put was more so for a demo project (‘my-test-app’) than something descriptive. I tried first updating app.json with new values for name and description fields while simultaneously bumping the versionTag. Then I redeployed and activated once more. The output of the commands seemed like it had been successful, but when viewing the app in the CDF UI interface, it still said the old name while also stating that it was last updated during my first deployment.Then I saw from the CLI that there was a ‘deactivate’ command. I wanted to try this in order to then see if I deactivated the one present and then deployed again now with a new externalId that it would hide the previous one and deploy correctly my one. But the wierd thing is that the output of this command says that there is no active version, while apps status

 When defining both data-model time-series nodes and DatapointSubscriptions on those nodes, cdf publish fails, because the data being subscribed to does not yet exist in CDF. This means we have to first push the .node.yaml files, allow the CI/CD pipeline to run, and then push the subscriptions. This does not work however because the moment both changes exist in dev at the same time, and we move it over to the next branch, the project won’t deploy. Does the toolkit somehow support defining data-model time-series and subscriptions on those time-series on the same deployment, or can it be implemented that nodes are published before subscriptions are made? ╭─ Deploy summary (dry run) ─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮│

I come from a data analysis background, specifically working on anomaly detection in power plant equipment operations. I find Cognite to be a great learning platform.I would like to suggest whether it is possible to have a sandbox environment where we can practice using data and apply our own logic. Recently, I received communication from Cognite encouraging users to implement their own anomaly detection ideas, which is a great opportunity to learn and contribute.Having access to a sandbox setup with relevant data would allow us to build and test data models for anomaly detection. This would be beneficial for both learning and practical application, especially since the platform is closely aligned with real plant operations.

Under the admin panel, in “Access Management” you are able to modify a group to provide them capabilities to access the new Flows apps, e.g., “apphosting”. By adding the read and run capabilities we have confirmed it is possible for users with these to see and run the apps.We want to replicate this in the infrastructure code, and have attempted to add “apphostingAcl” with actions for - apphostingAcl: actions: - READ - RUN scope: all: {} However, when attempting to deploy this to a project:cdf deploy $(pwd)/build-qaThe following error is received for the commandAPI error: Request failed with status code 400: Unknown field name:`apphostingAcl` at items.capabilities[15].?.The request body and response has been written todeploy_logs_2026-06-04/2026-06-04T06_49_09.086412+00_00.json for debuggingpurposes. When attempting to consult the documentation, I could not find a reference for this. So is this currently possible in

Hi Team,Our observation while storing duplicate entries in Cognite Streams:Mutable Streams - It discards the duplicate entries consistently.Immutable Streams - It sometimes allow exact duplicate entries (externalId and other fields) and sometimes it doesn’t.Even when we checked in the Cognite AI, it says it usually doesn’t allow duplicate entries but in some rare scenarios, it allows.Could you please let us know the behavior. If it allows in rare scenarios, please let us know the exact scenarios.Thanks,Rahul
