Hi everyone,We're excited to share one of the standout features from our Q3 release: real-time, multi-user collaboration in Industrial Canvas — now in Private Preview.The problem we're solvingUntil now, Industrial Canvas has been a single-user experience. That meant teams working on the same problem couldn't work in the same space at the same time — creating silos and slowing down team-based decision-making.What's newIndustrial Canvas is becoming a truly collaborative workspace, where multiple users can work together simultaneously — exploring data insights side-by-side and driving faster, unified decisions together. Where this creates value — real use cases (not limited to):Root Cause Analysis — multiple engineers investigate different parts of a failure simultaneously and consolidate findings instantly. Field-to-Office Bridge — field operators and back-office engineers mark up the same P&ID together, in real time. Meeting Facilitation — run operational reviews or shift handovers

As part of the September/Q3 product release, we enabled Smarter Search Results across all clusters except westeurope-1.  For westeurope-1, we’re currently working on stability improvements. To avoid introducing additional changes while that work is ongoing, we’ll enable Smarter Search Results there once those improvements are complete.  Smarter Search Results is improving how data is analyzed to provide more relevant and precise search results. See more information about this improvement in the linked documentation.

Dear Team,I completed 5 out of 6 courses in the Data Engineer Basics: Transform and Contextualize learning path back in January 2026. However, I am currently unable to proceed with the Data Engineer Basics: Transform and Contextualize – Assessment.The assessment is still showing as pending in my profile, and I am unable to access or start it.Could you please review my learning progress and enable access to the final assessment as soon as possible?Please refer to the attached screenshot for additional details.Thank you for your support.Mohan Narayanan

Hi,When working with an API it is possible to retrieve data as e.g. a json-file. Currently, the routines does not support this. Would it be possible for the routine to accept json-format (or other file formats) in the output? The image show that the routine fetches the data, but the string does not support it.   

Hi,We have built a Simulators Agent (Atlas AI Agent) with access to multiple Simulators Routines running through Cognite Connectors (PROSPER, GAP, and UniSim).Today, our setup consists of a single Azure VM with one instance of each simulator and its corresponding Cognite Connector installed on this VM. The environment is not auto-scalable.We have tested the queuing behavior with a single connector and observed positive results:Submitting 10 requests for the same simulator routine with different inputs results in jobs being queued, executed sequentially, and returned successfully. Launching the same routine simultaneously from 3 independent agent sessions also works without conflicts. Each session receives its results correctly.QuestionWhen we scale up to run thousands of simulations, we expect to deploy multiple instances of the same simulator and multiple Cognite Connectors of the same type.Does Cognite provide any built-in queuing, load balancing, or workload distribution mechanism a

Hi,We have some use-cases where we want an array of variables (inputs) to be passed as SET (not just one value). If I’ve understood it correctly, the routine inputs (SET) only supports one-value inputs (e.g. one temperature or pressure value).This is an example of the fields for flash calculations in WhitsonPVT. We would like to be able to do similar calculations consisting of arrays of temperature and pressures when running flash calculations through routines. Is it possible to add this feature?   

Hello, I recently joined Cognite and I am happy to start this learning journey! Looking forward to learn more about Cognite Data Fusion

We hit an undocumented behavior of the OPC UA extractor (version 2.38.0, Docker) that we'd like to confirm.Setup: cognite.metadata-targets.clean with assets: true, timeseries: true, relationships: true, plus extraction.update fully enabled. This had been running fine for months — classic asset hierarchy plus classic time series.What we did: we added the GA Core Data Model space option to the same clean block: metadata-targets: clean: assets: true timeseries: true relationships: true space: "<our-instance-space>"What we observed:As documented, time series switched to CogniteExtractorTimeSeries instances in the space, with datapoints available via instanceId. Not documented: classic asset creation stopped entirely, even though clean.assets: true was still set. We verified this by deleting the extractor-managed asset hierarchy and restarting the extractor: after a full startup browse, no assets were recreated — no error, no failure run on the extraction pipeline, nothin

Streamlit is an extremely useful tool for building apps and dashboards, but currently, anyone with the appropriate permissions can edit or delete the original source code.This creates the risk of accidentally editing or deleting someone else’s source code, and restoring it can be difficult.Therefore, we believe that adding the following features would enhance security:・By default, only the creator should be granted permissions to edit or delete source code. However, since there are many situations where you might want to designate co-editors or co-administrators, it should be possible to grant editing and deletion permissions to any member.・Users without editing or deletion permissions should be able to view and download the source code.Please note that these specifications pertain to source code editing under “Data Fusion” → “Build Solutions”; we do not believe it is necessary to impose usage restrictions on apps published under “Flows” → “Custom Apps,” and we believe the current appr

Hi, I am trying to set up a routine in GAP, but the run fails due to missing variable in the command, and I cannot set the value specifying which calculation to run. Can anyone explain how to fix this?This is a screenshot from GAP, and I want to select one of the Allowed Values:This is a screenshot in CDF showing that there is no field to enter that:The error message:  

Hi team, we're seeing what looks like a backend issue on westeurope-1 during the Cognite bootcamp.Environment- Cluster: westeurope-1- Projects: cdf-bootcamp-50-prod (also observed in cdf-bootcamp-43-prod)- Time: ~14:40 CEST, 1 Sep 2026Symptom- Transformations and hosted extractors report success / Running, but no instances appear in the data model (Flows/Search is empty).- The datapoints Cognite Function fails when querying the data model:  client.data_modeling.instances.list(...) ->  CogniteAPIError: Request had 1 constraint violations ...

Who we areWe run a web application for industrial bakery lines that uses CDF as its back end. It's used by both plant operators and management. We're currently migrating our data models to the Core Data Model, and while doing so we've extended it with views of our own — which is what we understood a data model to be for.While migrating we've hit a case where two things we need seem to be mutually exclusive, and we'd like to know the intended pattern.What we needTranslations for some units. Not all of them — a specific set where the label carries meaning for the reader. Our headline case is throughput. We measure, depending on the line and the moment, trays per hour, where a tray may hold several products, or baguettes per hour, or products per hour. #/h is correct dimensionally but doesn't express that variety, and our users need the right word in the right language. (A secondary, milder case: length:kilom has longName: "Kilometer", and there are no accented aliases in the catalogue —

Hi Cognite Community,we currently have a Streamlit Custom App hosted directly in Cognite Data Fusion that we would like to provide to end users for an upcoming testing phase.Our plan is to let the users test the current Streamlit version first, while in parallel we are working on migrating/rebuilding the application as a Flows app.However, this migration will still take some time, while the users are expected to start testing the Streamlit application in approximately two weeks.For the testing phase, we would therefore like to provide users with a direct link to the Streamlit application, but ideally without showing the surrounding CDF navigation/sidebar (Home, Search, Canvas, Charts, Custom Apps, etc.).The goal would be something similar to a standalone/full-screen application experience while still keeping the current Streamlit app hosted and authenticated through CDF.Is there currently any supported way for Streamlit Custom Apps to:hide the CDF shell/sidebar, open the application in

I’m trying to deploy a couple of Streamlit apps into Data Fusion.  I’m getting the error “Error during booting up: Program terminated with exit(1)” in the Data Fusion editor portal.I’d swore one app was working yesterday and I was able to publish, but both apps are giving this error in the editor portal.  I can publish, but I get the same error in Flows when trying to run the custom app. I’ve tried researching and it says to look at the logs, but I don’t see a way to view any log details.Any thoughts on how to debug this? 

To all the experts out there,When parsing a diagram, some annotations may be incorrectly assigned and overlap with the correct ones. For example, "Pump A-1" is correct, while "Pressure Gauge A-1" is incorrect.I want to reject the incorrect "Pressure Gauge A-1" annotation, but I cannot select it because it completely overlaps with the correct "Pump A-1" annotation. As a result, I cannot select and reject the annotation I want to remove. First of all, it is difficult to tell at a glance which annotations are overlapping, as the only indication is a slightly darker color. The annotations I pointed out below are overlapping.I would like it to work like Explorer, as it used to.
