Hi Everyone!I need to manage streamlit applications (read / update files) using the Cognite SDK or with the API.I was able to publish streamlit applications using the cognite toolkit, but I also need to read them.Tried searching the api-docs and cognite-sdk docs with no luck. Thank you!

In the process of initializing a new CDF tenant for one of our customers I am getting the following error when adding Assets Read/Write capabilities: 1 invalid capabilitie(s) are present: {"assetsAcl":{"actions":["READ","WRITE"],"scope":{"all":{}}}} (invalid capability - write access to the legacy Assets API is restricted) | code: 400 | Are core assets now restricted?

Hi Team, we have data in format like list of externalIds and space as key and value.  Like list of Json object in data model. something like [{externalId:well,space:slb},{externalId:well1,space:slb2}]So can we keep a field in model like violatedEntities: [JsonObject]Is it possible to parse all the externalIds and store it like this?Thank you.

Hello,  Is it planned to support RAW querying via CDF Grafana Datasource ?  Thanks ! 

We are now planning to integrate a large amount of historical data. The context about historical data and our data organization is in this topic:We create an interface WellState, which contains 2 properties: WellId and Archived, in order to propagate the Archived flag to every object in our data models.After integrated large historical data in our development env, we found that DataFetchingException always occurred in Daily(550K lines) and Operation(2M lines) in using GraphQL. And if using cdf_nodes to load Daily and Operation, the transformation will be blocked util that your session is closed.Info: Daily has many relationships and Operation has only a relationship with Daily. But We have also other 3 objects like Operation(big dataset and a relationship with Dail

Hello, I have two questions:When using cdf_nodes in transformation, does query optimizer take advantage of the container indexes? What we notice is it is not the case.  How can we run broadcast joins in transformation. Hints does seem to be working: https://spark.apache.org/docs/latest/sql-ref-syntax-qry-select-hints.htmlThank you!

To improve SQL performance, I want to use a CTE to get the IDs of archived wells and then update WellState (archived and WellId are in

I am facing issue of jupyter notebook getting crashed frequently. It is observed for larger data and surprisingly ML model training on smallest data chunks as well.Sharing the image for reference.  

Hello,We are querying the view WfAlarms (structure as given below) which has direct reference to alarmCode. When we are querying it for say 3+ months, we get the CogniteApiError, but works fine when it is 1month. This error is seen in our application deployed in production. We expect almost 2 million of records in this view. Can you help to understand what can be done to fix this issue ? Any configuration that needs to be changed. Let me know if you need any other details.1. Properties being queried from view - WfAlarms ErrorView:type WfAlarms @view(version: "2") @container(indexes: [{identifier : "entityName", fie

As of January 1st, 2026, the Rule-Based Coloring feature in Industrial Canvas will transition from public beta to private beta. The change will not affect existing users who have previously enabled and are using the feature on a daily basis. The feature will be unavailable for new and existing users who are not in the private beta program.No action is needed. If you have any questions or concerns, please reach out.Thank you,Andreea. 

Hi all, looking for guidance on two issues we hit with CDF related to timeseries visibility and datamodel queries.403 error leaking timeseries externalIds:when a user without access requests a timeseries resource, a 403 error is returned as expected, but the error body contains the externalIds of the timeseries. Those externalIds are sensitive and should not be exposed to users who don’t have access.Is it expected behavior that externalIds are included in 403 error messages? If not, is there a setting / configuration / log-level that controls whether identifiers are returned in errors? Any recommended mitigation or planned fix? Datamodel query returns datapoints from unauthorized timeseriesSetup: Created dataset_1 and dataset_2 Created two timeseries, TS_A in dataset_1 and TS_B in dataset_2 Attached both TS_A and TS_B to a datamodel Granted the user only t

Hi, Data models names are limited to 37 chars today. Is this a hard limit? Is there a way to extend this so we can have more possibilities for internal naming conventions? Thank you!

The “Ask a Question” feature inside the Canvas is very helpful—it allows users to quickly access specific documents and find information easily.However, I noticed that this feature is not available in the Industrial Tool – Search option or under the Data Management – Data Explorer tab. It would be very useful to have this functionality directly within the Data Explorer, as it would make the process more efficient and user-friendly without needing to switch to Canvas.What are your thoughts on this?Is it possible to consider adding this feature to Data Explorer in the future?

Hi team,I am looking for a way to trace data lineage in CDF. For example, if we have a table in RAW that feeds another table through a Transformation, is there a straightforward way to see where that data is being used downstream?Basically, I want to understand how to track which tables, transformations, or data products depend on a particular RAW table. Any native feature or recommended approach for this in CDF?Thanks!

I'd like to inquire about the current status of the monitoring functionality in the workflow orchestration. Specifically, I'm interested in the setup for notification emails. It would be helpful to know if we are able to receive notifications in the event of a workflow failure. Could you please provide an update on this?

Hello, We are using cdf toolkit to deploy our data models. We have a relatively a big data models that uses 478 views. Each time we deploy a breaking change our data model architecture (well centric) obliges us to redeploy a new version for all views. We notice a huge deployment time at the dependencies resolution step: 2025-08-19T09:34:54+00:00 WARNING [LOW]: Failed to create 478 views: One or moreviews do not exist: 'sp_dm_mud_brines_for_ops_real_wview:Activity/0.10'.. Attempting to recover...The overall deployment time takes 35 mins, this way bigger than our standard CI/CD job duration where we try to keep it under 10min at worst. Is there a way to optimize this please?  Thank you!    

I created an asset hierarchy with the Cogntie Core Data Model, then I created a custom data model through neat and I need to migrate the assets from the core data model to the custom extended data model, I tried creating a transformation but got the following error: failed with status 403: Properties [assetHierarchy_path, assetHierarchy_path_last_updated_time, assetHierarchy_root] are maintained by DMS and cannot be modified by end users. is there a way I can migrate/update the core data model assets to our extended data model?

The MQTT hosted extractor is erroring out and showing the following message: Internal database error: Session has expired: Session was not foundI’ve tried pausing and resuming the extractor, and modifying the configured sink, without success.

Hi,Context:We currently organize our data in CDF using a per-country partitioning strategy, where each country has its own space.This approach was chosen primarily to restrict data access by country in a fine-grained manner.On top of that, we expose data models grouped by Business Object, such as Well Architecture, Cost Model, etc.Each Business Object model aggregates several data objects under a common business theme, which also allows us to control access by business domain in addition to country-based access.We are now planning to integrate a large amount of historical data, which will likely increase our model size by around 4x.These historical datasets are rarely queried, but we want to make sure their addition does not degrade performance for operational data — both in query latency and data ingestion thro

Hello,I’m using a Cognite MQTT Extractor.I wonder if it is possible to publish with this client to the same broker I am subscribed to.Furthermore, I would like to know if it is possible to develop callbacks in a similar way to Python clients, for example : https://pypi.org/project/paho-mqtt/#callbacks Regards,Pierre

For metadata on assets (and other object types) in the app UI, the text is capped even though there is a lot of white space. Inconvenient when viewing it on a big screen and expecting to be able to see the whole string.
