Hi,We have uploaded a 3D .nwd model using the Fusion UI and noticed that the underlying processed 3D files (e.g., .glb, .reveal, .zip) are stored as file resources and are visible in the Data Explorer under the Files resource type.I couldn’t find any documentation or guideline on how to assign security categories to hide or restrict access to these files for end users. I also tried using dataset-based access control, but I’m looking for a better or recommended way to handle this.Appreciate your guidance or suggestions.

The python extractor utils requires the config to be stored as a local file there is not way to pass it directly as a string/yaml object. This makes it quite cumbersome to use as not all our deployments have access to local file storage for config files.Is there a way to add support for the config to be passed as an environment variable? Reading config from env example:

I am getting following error when ingesting files from SharePoint site to CDF. send_request_body.failed exception=LocalProtocolError('Too much data for declared Content-Length')Anything I need to specify in .yaml file to allow content-length? Also how do I trace which file is causing the problem. I changed Logger to DEBUG level but still don’t see the file name info.Thanks,Zuber

Hello, In our project, we need to use TIMESTAMP_LTZ data type for our timestamps. This data type is only available in Spark starting from 3.4 version. Is it possible to upgrade your version (which is 3.3 I believe) to 3.4 at least please? Thank you

Hello, We envision to implement a versioning based on minor and major version of our data models. So a data model version will be presented with two digits: <Major>.<Minor><Major>: incremented when we do a breaking change that is not backward compatible with the previous one and we know that it will break our consumers queries. Exp: delete an attribute in a view in the data model<Minor>: incremented when we do a change that is backward compatible and consumer queries will not break. Exp: add a new field. Is there a way to get a graphql url that maps always to the latest minor version of a given data model? This will avoid our data model consumers to redeploy their application every time we increment our minor version.  Thank you!

Hi all,I have a question regarding the use of nested attributes from linked objects when defining indexes.In my model, I have an object Cement that has a direct link to another object called ScenarioContent.I would like to use the attribute ScenarioContent.Type as part of the index on the Cement object.This is particularly useful, because I use views that filter Cement instances based on ScenarioContent.Type. For example, to expose only planned scenarios, I use the following rawFilter in a view:@view(  rawFilter: {    nested: {      scope: ["Cement", "ScenarioContent"]      filter: {        equals: {          property: ["ScenarioContent", "Type"]          value: "PLANNED"        }      }    }  }) Question:Can I use this nested attribute (ScenarioContent.Type) in the index

Hi, I did run transformation of assets and it worked first time successfully but today when I had a look, found a failed run and looking at logs, it says below error: Request with id 0b54c004-c667-9eab-a8c3-0a0047128fe1 to https://westeurope-1.cognitedata.com/api/v1/projects/cdf-ABCD/models/instances failed with status 400: Duplicate node externalIds for space 'icapi_dm_space' present in request: OSPRFIDRTO109:off_spec. Any idea how to fix this? and what is this error actually? 

Hi Community,I am using a toolkit and I am doing some transformation from RAW to the Data Model. From the Documentation Online, I only see example on how to apply the toolkit transformation to legacy tables (assets, events, timeseries,etc)This is sample of transformation format for toolkit:  Anyone know what is the configuration if we want to transform to Data Model? How to apply the space name and external id? Thank you.

Hi everyone,I'm currently using a nested filter in my view, and everything seems to work correctly — except in the tabular view.Here’s what I observe:In the tabular interface, the table shows 0 objects. However, when I click into the table, I can actually see that the instances are present. 

Hi Hub, We have some backend code running as a Github Action that fetches events using `clients.events.list` over a period of 1 year. The fetching is of course chunked into smaller time frames to avoid memory overload. This has worked just fine until recently where we are frequently encountering aCogniteReadTimeouterror, which can be traced back to the following HTTP request error:requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='az-ams-sp-002.cognitedata.com', port=443): Read timed out. (read timeout=30)The error occurs inconsistently and not necessarily at the same point in time of the workflow run. Have there been any recent changes/restrictions in the Cognite SDK that could explain the cause of the issue? As mentioned, some weeks ago the workflow succeeded without problems. For additional context, we are using multiple threa

When deploying a function with the SDK you can specify the source code “folder” as a parameter. I have used this to deploy the functions with my own python module which is just a directory with some py files. I want to migrate to using the toolkit, but I am not sure how to deploy with the source code folder I want as I do not see a way to specify it in the yaml file. Can anyone help with this? I have multiple Cognite Functions that I want to deploy that all access the same source code I have written.Thank you!Sebastian

¿HOW COGNITE DATA FUSION HELP US TO IMPROVE THE ENEERGY EFFICIENCY IN AN INDUSTRIAL PROCESS?

I see there is a fork for ToolJet in the CogniteData git repo.  I’m curious to know if Cognite has done anything with this branch and if so, how it’s being used within the product. Thanks!

We are trying to implement automatic monitoring over our transformations in CDF. We are doing this by running a transformation and a monitoring function in the same workflow, where the monitoring function is dependent on the transformation being finished.Then we retrieve the sum of updated and created events like this: def _created_and_updated_sum(self, transformation_external_id: str) -> int: """ Get the sum of the number of created and updated events in the last transformation job. If there are no finished jobs, return 0 instead. """ transformation = self.cdf_client.transformations.retrieve( external_id = transformation_external_id, ) if transformation is None: raise ValueError(f"Transformation {transformation_external_id} not found") if transformation.last_f

I noticed a few misses / potential improvements in the alerts & monitoring section of Cognite charts - Was wondering if anybody else had similar experiences?Email alerts always come in UTC (Considering we are based out of India, we may miss important alerts because of this). Let's say I have an Asset where I have generated a chart (in our case a particular well from a particular lift type showing critical parameters). A filter-based option where I can just switch Wells showing - using the same parameters as tagged before.

Hi,I would like to ask if Cognite Maintain or CDF can show the available bill of materials on equipment in the source system(for eg. in SAP).For example if technician can view the BoM on P&ID and the most frequently consumed materials on equipment, e.g compressor. 

A common setup that we have at Cognite is having 3 different environments: development, test and production. We have one specific Cognite Data Fusion (CDF) project for each of these environments. This setup allows to develop new features without interfering with production data. Also, it makes the deployment of new features to production much safer, since they are tested before.Sometimes, you still want to have the data you used during your tests, in your production environment. For example, if you extracted some data from sensors and saved them as time series in CDF, you may want to keep this historical data when you move to production. Same goes with files, assets, datasets, functions etc. Another example could be the replication of the data from a full production CDF project, to one of your customer’s project, containing only a subset of the source one.At Cognite, we have a python package (available at 

Dear Cognite Hub community: We are very happy to announce that our Cognite SAP Extractor is now generally available to CDF users!The extractor connects to OData V2.0 endpoints in the SAP NetWeaver Gateway, making use of many pre-built integrations available in S/4HANA and saving considerable implementation time, while also natively connecting to the SAP data you need in a standardised manner.To get started,  download the SAP Extractor from the “Extract Data” page directly from CDF. The documentation, including Server Requirements and how to set up your SAP extractor is available here.We have also prepared a short demo (less than 4 minutes long) showing the steps needed to set

ContextQuerying views with a large number of instances (>1 million), we frequently encounter query timeout issues. This has become a critical bottleneck affecting application performance and user experience. To mitigate this, we introduced on the app layer a pre-query caching strategy:Before sending a query to Cognite, we aggregate the number of instance spaces for a given view using the endpoint /models/instances/aggregate. This result is stored in a cache layer. When a query is initiated, we check if the user included a space filter. If not, we append the known relevant spaces from the cache to the query filter. This approach has significantly reduced timeouts across our applications. However, it introduces new challenges:One request per view is still needed to fetch associated spaces. Cache invalidation must be managed periodically, especiall
