Containers, Spaces and Instances

I have the following question regarding Containers, Spaces and Instances. Let's say I have a Container named Well in the space A and all its instances are created in space B. When I delete container Well in space A and recreate it (because I want to change a column name for example): Does instance in space B are deleted as well? If they are not deleted, If I rerun the transformation to populate the new container again in space B with the new schema (same external_id) what state should I expect my instances to be in ? A merge of old and new schema? What is the best practice ? To delete container in its space and its instances in all spaces also? Thank you!

Cognite Data Fusion Toolkit

modules for infield, inrobot and maintain

Hello Team, We are deploying CDF resources through toolkit. As part of it, we are also planning to deploy inrobot, infield and maintain from same pipeline. Can you please let me know from where we can get toolkit modules for these Cognite Apps. Also, how the versioning is done for these modules? Can I automate the process to fetch the modules from some repo or shared location in my pipeline?

Hosted extractors needs monitoring, otherwise we can't allow them in productionNew

All hosted extractors needs some kind of monitoring like extraction pipelines. This is supported for on-premise extractors and we don’t understand why this has been left out of the hosted extractors.We have requirements for monitoring all extractors and integrations we have in production, as I assume a lot of other companies does as well, but without monitoring hosted extractors are not an option at all. We simply can’t use them, it is unacceptable to skip monitoring.We would very much like to use them, but in their current state they’re a selling point for a powerpoint presentation with no real applicability.

Data model filter on length of attribute value

Hi all,I am building a solution model on top of a domain model we already have in place for a project.The domain model contains all the instances we have in the project, but this consumer is only interested in a subset and would like some filters in place to ensure that they are only getting the subset of interest. One of the requirements is that a certain property is according to their project standards and has a minimum length for a property. I see that there is a Range filter to check if a numeric property’s value is within a specified range, but is there any way I can add functionality to get the values length for this property?

Is there any way to ODBC DNS for Snowflake Extractor instead of putting username and password in YAML?Parked

Hello, I have trying to use the ODBC extractor to pull data from Snowflake, I could do that by following instructions here https://docs.cognite.com/cdf/integration/guides/extraction/configuration/db/#-snowflake However, this requires me to put passwords in YAML config. Is there anyway to use DSN from ODBC instead? I see that connection-string parameter is not supported when I choose type as snowflake. Thanks!

CDF File Extractor for SharepointParked

Problem Description: Cognite File Extractor for Sharepoint is not able to recursively retrieve documents from a Sharepoint site where site and sub-sites, e.g. Document Control System Alternatives explored: Provide Sharepoint URL as mentioned in documentation for site (Sharepoint Online | Cognite Documentation) Results: no errors, however, no documents are loaded Evaluation: recursion does not occur from site-level down to the document or folder level where Sharepoint stores documents Provide document library and folder / sub-folder Results: working, however, sustainability not ideal Evaluation: will require potentially >100 URLs to be configured and kept up-to-date in case of new document libraries or folders created or deleted Recommended enhancement Recursion from root node (Sharepoint site). E.g. if site URL is provided recursion should go through each sub-site (if present) to document libraries and sub-folders to retrieve documents This should be treated as high-prio

Cognite Data Fusion: Missing values in a Time Series is reflected in Synthetic Time SeriesImplemented

Problem: If one or more of the source-time series are missing data-points they will also be missing in the synthetic time series output.Would it be possible to add an option to supply a default “not available” value for missing data-points which could then be used by the API to calculate a partial result?Source:

DatapointsSubscription: Expired cursorParked

I understand that updates older than 7 days may be discarded from the endpoint, which is perfectly fine. However, I’m wondering if it’s possible to determine when a cursor is older than the given limit, since updates older than 7 days are discarded. Based on my understanding of your Subscription API, it would simply continue iterating over the oldest available updates on the endpoint, which could result in missing important updates that occurred between the time of my cursor and the current oldest update. For the Subscription API to be fully functional, I believe it's essential to either receive a notification or an exception when using an expired cursor, be able to determine the age of a cursor, or somehow be assured that iterating from a cursor won't lead to lost data. Knowing the age of the cursor would be preferable, as it would allow us to gauge how much margin we have, but it should also be possible to receive a notification if an expired cursor is being used. Is this currently p

Flag inactive / deprecated time series - and only display active ones by defaultParked

Once in a while we make changes to our telemetry setup in such a way that certain time series get deprecated. This happens when we change control systems, or make changes in our telemetry pipeline, or even discontinue operations at a location. We want to have the “deprecated” time series available in CDF, but it would be useful for us if these would not by default appear in search, or in the asset hierarchy, or through grafana and other solutions. It would be useful if there was a way to mark a time series as deprecated or as only containing historical data - and that in order to have the time series returned in search or list operations, the user would have to make an active choice to include those time series. My suggestion is an “isDeprecated” property on each time series. There are other solutions to the problem, but these all seem to make it more difficult for the user than simply not showing deprecated time series by default:Metadata field - isDeprecated (boolean) Move deprecated

Establishing Relationships Between Domain Data Models and Asset

If I want to establish a relationship between a specific data model (not the core or enterprise model) and assets like a "function location," Do I necessarily need to bring all the views from the core or enterprise models into your domain data model?The goal is not to extend the core model but to create a reference from my domain data model to the asset, possibly using node_reference.For instance, if I have an inventory and want to relate materials to a local storage (which is represented as an asset in the enterprise data model), could I define a property in my domain model that references the enterprise asset.Example:graphqltype StorageLocation { location: String plant: CogniteAsset # Reference to the asset in the enterprise model } In this case, I am just creating a link between my domain model and the asset without needing to extend the enterprise model or bring its full view into my domain model , works?

Hosted extractors, missing and confusion UI elements

We would very much like for a new column to be added to this view, “extractor type”. Currently there are no indicators as to what type of extractor it is. For the developers working on the extractor this is not an issue because they know, but for others that just want an overview this is somewhat more difficult as we would need to click in on every single one of them to find out. Sometimes we would like to just see all REST extractors, or all MQTT extractors and so on. Another point is the throughput: “0 datapoints p/hr”What does the “p” stand for, is it “0 datapoints per hour” because if so the p is redundant as the standard use of “/” already signifies it. Also the SI unit for hour is h not hr. E.g.: km/h (km/t norwegian), m/s etc.

Point cloud rendering issue

Hi All,We are encountering an issue after uploading E57 point cloud files into Cognite Data Fusion (CDF). The rendering quality of the images is quite poor, and we're unsure if we're making a mistake during the upload process.Has anyone else experienced similar issues? If so, do you have any solutions or recommendations to improve the image quality for point cloud in CDF?Please feel free to share your insights and suggestions.Thank you!

Data modeling transformations

hello guys, I wonder how do you populate data model directly from the dataset? so i have ingested all my timeseries data into my dataset and then i want to run transformations using this dataset as a source but how do i get the actual values from the data points and can you filter just to extract certain timeseries data? this is the query i am running at the moment: select cast(`externalId` as STRING) as externalId, cast(`name` as STRING) as name, cast(`description` as STRING) as descriptionfrom `_cdf`.`timeseries`; what i want really is to import all my timeseries data from my dataset into my data model and then continue building.

External ID doesn't work when copying from Fusion UI

The external id of some time series contains special characters. Should they contain special characters, no, but that is not the issue here. As long as CDF allows special characters in their ID’s it should also have support for them in the rest of the system. When you press the copy button in Fusion you don’t get the special characters, and without those characters the ID is invalid and cannot be used. Hence the copy button does not actually copy the external ID, it alters it and that is an issue.# The actual external IDLIMS_Skarv_Analysis 9-ion analysis_SP 44-AP-0027 - DS - 2. STG\xa0SEP_Param Sulphate, SO42-_Unit mg/l# Copied from Fusion UILIMS_Skarv_Analysis 9-ion analysis_SP 44-AP-0027 - DS - 2. STG SEP_Param Sulphate, SO42-_Unit mg/lThe fact that the external ids contain these characters to begin with is a different issue we are looking into.
