I have a question about contextualization.In my setup, I have a functional location with a machine, and under the machine, there's a sub-station. When I contextualize a document related to the sub-station, why isn't it directly linked to the machine level and the functional location? I understand that I manually contextualize it to the specific station, but since the station is part of the machine and the functional location, it should appear there too.I think there's a missing link in my data modeling between the functional location, machine, and sub-station. What methods can I use to ensure that when I contextualize a document, it shows up at all levels of the hierarchy linked to that machine?

We intend to effect 3 breaking changes to the Records API over the next couple of weeks of the Private Beta program. These changes may require updates of your test procedures. /streams API “settings” attribute will be required Summary: Modifying the Cognite Streams API.From when: After July 15, 2025Description:The Streams API provides a broad spectrum of functionalities, but it's important to understand that these capabilities are not mutually exclusive; enhancing one often means adjusting another. For instance, if a stream is designed for permanent data storage, it will offer unlimited record retention but a lower maximum ingestion rate. Conversely, streams built for temporary data staging will support significantly bigger ingestion rate but only for a brief retention period. Similarly, you'll choose between mutable streams (allowing record changes) and immutable streams (optimized for high volume and speed).Because of these crucial distinctions, it's essential for users to be fully a

Hello, We are considering storing a relational database table with more than 100 columns as Records.Since the maximum number of properties per container is 100, we need to define a single table across two or more containers.In this case, I would like to know how to write a query that allows us to freely filter records that have properties defined across multiple containers.Our goal is to query the Records data in a way similar to executing SQL on the original RDB table with over 100 columns.Based on my testing, the behavior was as follows, which is not what I intended:When using only properties from container A in the filter or sort: only records of properties from container A are retrieved. When using properties from both container A and container B in the filter or sort: an empty JSONL is returned.If this cannot be resolved with a single query, I would appreciate advice on what kind of post-processing could help achieve the desired result.

i want to take export of one table to another table but facing this datatype error .also tried with multiple datatype (like string , float and Bigint ) still same issue is coming.  

Hey everyone! 👋 I've been diving into the world of CDF data modeling for the past couple of weeks, and I thought I'd share what I've learned so far in a way that's easy to understand. First off, let's talk about the term "Data Modeling." It's everywhere in CDF - in API endpoints, UI, docs - but its meaning can vary depending on where you look. After some digging, I've figured out what it means specifically in CDF. Essentially, it's about organizing, storing, and working with data in a way that's perfect for handling complex industrial scenarios. Think of it as the foundation for unleashing the power of Cognite Data Fusion on your industrial data. So, what exactly makes up a Data Model in CDF? Let's break it down: Space: Think of it like a folder where everything in a Data Model hangs out. Containers, views, instances - they all belong to a Space and have their own unique ID. Containers: These are like the storage units for properties. They live within a space and hold sets of proper

Hi,I would like to update data to the EDR. The EDR has a build in tool to upload data, but I would like to use the API. As I understand it is not officially supported, but we would like to give it a try as we have hunderds of files we would like to upload.Before I asked my questions by e-mail, but I am directed to this hub to ask my questions, so there we go: File upload:I'm using the client.files.upload() function [1]. It seems to work when only the file path is provided, but I'm unsure whether this is sufficient or if I should be populating more of the optional arguments. Here's what I'm looking at: path external_id name source mime_type metadata directory asset_ids source_created_time source_modified_time data_set_id labels geo_location security_categories recursive overwrite  name: It appears this is automatically assigned based on the filename, is that okay?directory: This seems to default to the dataset ID, but I’ve run into an error when using 968ca

Whose idea was it to hide the dropdown behind the filters? 

Does it make the data available for optimal maintenance scheduling, or does it automatically generate maintenance plans based on that data? Does it predict failures?

Greetings,I was testing out the new Document Parser. Sometimes I would have a response saying the following: We had trouble parsing your documentOur team has been notified and will look into the issue. If you get stuck, contact support for help. Occasionally, I would get a successful parse, but I also get these failed parse jobs. I am unsure of the cause of the failure or whether the failure is preventable on the client side. I was wondering if someone could provide insight as to why the failure might be occurring.Thanks,Gabriel

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:

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 definition of Cement?If this is not currently supported, is there a recommended alternative to support performant queries on this kind of filter?

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.

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 threads to fetch events in parallel over metadata, for events within same time interval. Also, we use multiple cores to parallelize fetching and subsequent
