Hi team,I have the following questions,How does CDF handle unit of measurement. Is there a concept of storage unit system and display units system Eg; If a certain time series dataset have Celsius scale and other have Fahrenheit and kelvin scale. How does CDF store these in dataset and does it offer functionality for conversion.  If I want to build a chart with multiple time series have data with different units, does CDF offer unit conversion on the fly so that I can have everything displayed in a different units? I would like to have a comprehensive documentation for it.

Hi,I was wondering where I can find information about how to set up the permissions for a file extractor reading only files from a few sites in SharePoint, i.e., not giving the extractor access to all sites. I have solved it using the GraphAPI, but this is quite cumbersome, so I was wondering if we have documentation on how this can be set up. I’ll post my solution below for clarity on how I solved the issue:_______________________________________________________________________________You will need to create two applications. One that is used in the file extractor and one to give access to the file extractor.Register the File Extractor App: Go to the Azure Active Directory portal. Click on "Azure Active Directory" then click on "App registrations". Click on "New registration" to register a new app. Grant API Permissions: Once your app is registered, click on the app's name to go to its dashboard. Click on "API permissions" in the left panel. Click "Add a permission". Choose "Mic

When I use the search function in Data Explorer it shows information from other locations that I am not interested in.  How can I search and show results only for my location?  Thank you.

Hi There, We have multiple CDF transformations running on schedule for every 15 minutes. Sometimes these jobs are taking more than 15 minutes and leading to Transformation failure with an error - ‘A job already runs for this transform ’. Is there any provision for us in CDF to not run a job/transformation while it is running already. 

Is there any use cases available and/or documentation with examples about configuring the PI extractor?I have found the documentation available in the web lacks information with more robust examples.Also some of the videos i have seen so far are very very basic that seemes a waste of time to watch cause they can be resumed in one phrase cause they briefly tells you what the extractor do but they dont tell how to get it to work which is what we need as engineers, a step by step guide with better examples, using fictionary data and examples could be a good starting point so we can just follow up the guides and set up instead of being crating a lot of tickets which would be reserved for troubleshooting, etc. Thank you,

I would like to make you all aware of a new tool that is now in beta: The CDF Toolkit. The toolkit comes as a python package with a CLI tool, cdf-tk, and a set of templates that can be deployed to your CDF project to get started. This initial version is focused on Infield deployment, but can be used for any type of CDF project to manage your CDF configurations and resources as code. Head over to the beta group to check out the latest small demo videos we added and test it out!

Hi,I’m trying to search for signals where I know some keywords in the name string. I’m not interested in any fuzzy matches but rather just like to see only results which contain a certain phrase. This seems not to be possible unless I activate fuzzy (which then gives to many results). Is there a way to activate “partial match” but without having fuzzy search activated?

Hi,Is it possible to display stepwise connection between datapoints in Charts rather than the standard linear interpolation?Thanks!

Hei Dear CDF usersAre you a user using charts for data science purposes / tasks or an active user of python code / jupyter notebooks ? We would love to talk to you as @Lars Moastuen would like to better understand your needs and current workflows. The team is currently working on a jupyter notebooks integration with charts and would like to better understand the needs there. Please feel to comment in the thread below if you are an user using charts for these purposes.

Greetings,I would like to get a view of which files uploaded to CDF through extractors have not been completely uploaded and only partially uploaded.In order to do this, I wanted to write a python script that compares the files sizes in the RAW metadata tables with the actual file sizes in CDF. The question is, is there a way to retrieve file size directly of a file in CDF through python SDK without having to download the files locally?Thanks in advance

As of today I think the Python SDK is only accessible via pip. While I can install a pip package into a conda environment, I don’t really like this solution. Are you planning on releasing a conda package for the Python SDK?

Hi, I'm Iñaki and I've been in the digital industry for more than a decade learning and helping customers in their Digital Transformation journey.For industries like Oil and Gas and Manufacturing it feels like I’m embarking on an adventure with every customer having its own unique complexities. But it's the constant mix of challenges, opportunities and excitement that keeps us all on our toes and motivates me. These industries are all about growth and staying in the game, and they know that embracing the digital era is the real deal.Over at Cognite, we're all about guiding organizations through this wild digital journey. Our expertise? Well, it's a combo of what we've learned from our customers and our deep dive into industry best practices. It’s like putting together a puzzle when it comes to integrating all kinds of data into these massive data lakes. Is it complicated? Yes, but it’s worth it.To really unlock the full potential of digital transformation, industries need to dig deep t

Hello CDF developers and users,Following feedback about the best practice examples provided in the documentation for how to use Parallel Retrieval / Partitions, Cognite has updated its documentation to make more explicit the limits in place for how many partitions that can be used in a request.  The document now makes explicit that a maximum of 10 partitions is supported.This guidance is found in the Pagination section of the Developer GuideIn conjunction with the updated guidance, limit enforcement will be put in place on the Assets, Events and Files APIs, to ensure predictability of performance with these APIs, effective from 1st February 2023.  Requests calling for more than 10 partitions will return a HTTP 422 ‘Unprocessable_Entity’ error message.  Similar limits will be rolled out across all CDF backend APIs, and details of these limits will be provided in their respective resource type descriptions.For any existing client applications that are calling more than 10 partitions, the

When I upload a file into Classic data model, how do I associate that file object to Flexible Data Model (FDM) object and retrieve the file object data using Graph API from FDM.   

I am looking for information related to 3d models. I would like to explore does reveal/cognite supports programmatic change of animation on 3d models which are uploaded to cdf. What i am looking for is, i have 3d model of pump and would like to change the animation speed depending on the speed i get from my api (basically real time speed which i get from my api). Does it possible ? If so could you guide me to example code to how to do that. Also the uploaded 3d model in cdf is not displaying like how the original model that was uploaded. After uploading into cdf its not displaying with colors and animations, could you tell me why it is like that ? Thanks 

Hello! Was looking around and cleaning some data, and came upon the realization that I can’t find out of you can access Cognite resources that are not contained in a dataset. That is, is there an ability to find/fetch/list Cognite resources that are “floating free”.I have tried setting  data_set_ids  And data_set_external_ids  To None, but this is the same as not having specified it. 

Hi, I’m trying to add more fields to Dataset’s property, and would like to display them on the UI. Beside the existing fields (Labels, Owners, external ID, etc...), is it possible to display custom fields on the UI ( similar to metadata’s consoleLabels, consoleOwners). A good example would be how metadata displayed in details of file.

Looking at API documentationhttps://pr-411.docs.preview.cogniteapp.com/api/v1/it seems one can not build an automated pipeline to create and update 3D model only using python SDKs?I aim to make a pipeline using cognite function and python sdk for nightly update reading files from SharePoint and upload or update 3d models in cdf.If its possible, where I can find the guiding document?

I have provided the essential credentials within the config.yml file in the OpcUaExtractor config folder, however when run it get this error. How can I fix this?

Hello Team,I am working on creating POC on PROSPER Connector I checked documentation of Cognite Prosper Connector. Connector is provided by Cognite, but where can I get simulator for POC purpose?Also in connector configuration, where to provide simulator details or simulator name?  

If there are large number of instances in a view, wont that load in the fusion UI? Can’t this be fixed with trimming with some max limit and still display?  

Hi team, I’m working on OPC UA Extractor. I have configured metadata-targets and configured metadata-mapping.I’m not able to see the metadata along with timeseries data.Please find the configuration in attachment and screen shot in CDF how timeseries data looks like. please let me know if any additional configurations need to be done to see the metadata along with timeseries data. 

Hello,What are the best practices around setting the max-workers for a sdk. If I do not set the Global Config all the default values for workers and retries would be picked correct ? Can you give any reference on how we can set GlobalConfig, I mean I did not see any way to pass the GlobalConfig to ClientConfig ?

Hello, is it possible to test the  CogniteAuthError using monkeypatch context manager  ?Regards ,Hakim Arezki
