Are ANSI escape sequences planned to be added to the Cognite Function logs? For now, it seems to be impossible to make the text bold or change the color of the text inside the function logs. 

Hi, There are raw data files which are used to perform computations (yield tracking measures ) that uses tons of input data attributes to compute the metrics. Currently, VBA macros (excel) is used to perform the calculations and publishing the outputs. WE have to transfer the computation within CDF. Can we use cognite functions in this regard?. Is there a way to create python script that can perform these calculations within the CDF. If not, should we create some external cloud based construct like Azure functions or Lambda routines?Please share some examples are snippets that can help to perform this project task.

I have been using RAW tables and creating a final table out. After creating a transformation, I could see the number of rows as ~8000 but that's a wrong number. After changing the transformation a bit, now I got the correct number post running the transformation which  is around 4000 but the final RAW table isn't changing.I could see that the table isn't being overridden with the new data. Can anyone explain me why? Thanks in advance!

Hello team,We have ingested 15671 instances on an indexed model.While trying to view the data on the data managment tab on the fusion UI, we are getting 408 error.When we try to query the data through GraphQL, even if we apply limit of 1 we are getting the same response.Error message: {  "title": "",  "message": "Client request(POST https://westeurope-1.cognitedata.com/api/v1/projects/slb-pdf/models/instances/query) invalid: 408 Request Timeout. Text: \"{\n  \"error\": {\n    \"code\": 408,\n    \"message\": \"Graph query timed out.

If I have view B which implements view A, in the definition of view B do I need to list the properties (e.g. container mappings) that are “inherited” from A? I noticed that if I don’t list them, this works fine the first time when view B is created (I can see the inherited properties automatically included), but if I try to update view B (even if nothing changes) the call fails saying that there is a change in the property list and the version needs to be changed. I’m assuming this is because the inherited properties are missing from the definition. Is this behavior by design and I have to explicitly list the properties, or would it be considered a defect?

HI, May i know how to schedule a refresh in Power BI for Cognite as i am facing below error?When i try to schedule, i see it is disabled for me.I tried to install the gateway locally as well but it says installation failed.While establishing the connection with CDF on PBI desktop i get pop-up as third party connector. Does that mean PBI service doesn't support scheduling for Cognite?Please help.TIA.Regards,Arati

Hello, it’s kind of easy to get all edges via rest api, but how i can filter them by start node? It’s not clear from documentation how to create such filter. Or any other approach using rest api will help me.{ "instanceType": "edge", "limit": 1 "filter: { "property": [], "value": "value" }}My filter is not correct here, but what I want is to filter all edges where “startNode”: {“space”: “name-space”, “externalId”: “some-id”}

Hello Team,i have deleted some of the events from cognite but still i can see its present and when i click on that then it’s giving resource not found. can anyone please help what can be the issue.and also I am trying to delete all that also not able to delete due to previous issue.PFA. 

Is there any known limitation in cognite-sdk-dotnet to be consumed in enterprise solution?

Could you please suggest how to limit source?

I was trying to upload a machine learning model file in pickle format of size 5GB. I observed that whenever the file is getting uploaded, the size of the uploaded file is 969 MB. The entire file is not getting uploaded. Only a part of it getting uploaded.Are there any restrictions on size for file upload ? Can we increase the that restriction while uploading?

Currently, we choose the Instance Space same as Data Model ? What is the purpose of Space ? When we need to create one different with data model ? thanks :)

while using python sdk 5.10.5 and downgrade versions getting issue like 'CogniteClient' object has no attribute 'datapoints'.With latest version getting error while hitting micro service. Please find below  file for your reference.

Hi  In the current Cognite Infield desktop version, is there a limit on the number of characters for the synthetic tag names, before it displays “….” at the end? If so, what is the limit?We didn’t observe this in the mobile version, which seems to display full tag names that are longer than 40 characters completely (Some of our tags are ~40-50 characters long). But were curious with the desktop version, when the synthetic tags go “...” at the end and seems to hit a limit?Also, assuming this wouldn’t be a case in Infield 2.0, where there is a lot of expected improvement in space/layout. Thanks 

I find it useful to be able to filter CDF resources by their source system.How come Assets, Files and Events have a “source” attribute, while time series and events do not? I assume then, that in order to properly filter by source for any resource type, it might be best to rather add “source” as a metadata key for any resource type, rather than use the attribute field which is not available for all resource types?Btw., for the Relationships resource type, “source” has a different meaning than it has for Assets - I suppose this could cause some confusion?

In the Data Foundation-project; there is an understanding that times series data will be represented in accordance with OPC-UA data model using the FDM (DM) functionality in CDF. Is there any issues here in relation to the limitations in FDM stating that there is a limit of 10 million instances? Or will it be designed so that this will not be an issue?

Hi,I’m going through the Python SDK- CDF Transformation module in the  DATA ENGINEER BASICS - TRANSFORM AND CONTEXTUALIZE course.While I’m able to create the Transformation  object, I’m unable to run due to some Authentication issues. When I’m trying to run using the below code:client.transformations.run(asset_transformation.id, wait=False)I’m getting the following error :Transformation job could not be created.Error code: 403API error: Invalid source/destination credentials: Could not authenticate with the OIDC credentials. Please check your credentials.Request ID: 1a470c41-9001-989b-8f97-a2aaefdfd098Is it due to some recent change in the Oidc credentials defined in the notebook currently? 

Is it a good practice to execute transformations from a Cognite Function?Our team implemented a Cognite Function which executes transformations on tables from Cognite RAW. We chose this solution as we wanted to parametrize the SQL query of the transformation, essentially applying a different filter on raw tables every time.Also, it would easier for the end user, e.g. a plant operator, to provide a JSON input to the function then to edit the query every time in multiple locations. E.g., if the JSON is:{ "plant": "Plant.1", "equipment": "equipment.1"}the user can just change the ID for the plant and equipment. Furthermore, these values can be validated by the function before making the replacements in the query and executing the updated transformations.Let me know your thoughts!

Hi Team ,I am getting data set id validation error while trying to deploying functions.i have earlier deployed functions before using the same dataset id on that particular instance.but now suddenly getting the below error though i have not done any changes to the existing setup.Please help me here. Regards,Nidhi N G

Hi, I would like to understand the relationship of OSDU x OID? Are they competitors, the differ on, pros x cons.. Thanks in advance..

Hello Team, Now the Python SDK supporting the cursor parameter or not? Regards,Ayushi.
