Are you ready for a citizen data scientist adventure?

Cognite's Industrial Digital Academy (IDA), available on Cognite Academy, offers several courses to help you upskill and close any knowledge gaps to understand the value of CDF better.Today, we are eager to present the Data Science Fundamentals learning path we created with Cognite's data scientists. Some of our customers already had a pre-run, and their feedback is making us proud, so we recommend that you try it out. Take this opportunity and learn about data science from an industry point of view. You will be guided through a set of courses showcasing how data scientists solve industry challenges using industrial data.By the end of this learning path, you will: Understand basic principles of data science from an industry point of view Realize the importance of data science workflow Understand the value of understanding the business problem Be able to compare and analyze various data science use-cases  Understand the evolvement of data science, data doers, and citizen data sc

Maintenance Windows for Assets and Files - June 2021

Database migrations - assets and filesCognite plans to migrate data from Cloud SQL databases in our Google Cloud-based CDF clusters in a two-week period starting June 25, 2021. We plan to migrate the databases containing data for the assets and files resource types. The migration for the two resource types will occur on different days.  We will email customers the exact time of the maintenance window for their cluster, CDF project, and resource type.  Why is this database migration needed?Cognite has recently made CDF available on Azure in addition to Google Cloud. The code running on Google Cloud is currently dependent on database options only available in Google’s public cloud.  Migrating these databases enables us to run the same code base in Google Cloud and Azure, allowing us to bring recent improvements in our Azure implementation to customers on CDF projects hosted on Google Cloud.   APIs in read-only  modeWe will set the API for the impacted resource types in read-only mode dur

Test out the new Interactive Engineering Diagram Flow on Fusion!

Hello Developer Community,The Contextualization team at Cognite released an experimental interactive engineering diagram flow on fusion.cognite.com  . The old interactive engineering diagram flow still exists in fusion.cognite.com, however, it will be replaced with the new flow come August 1st. Thus, we highly encourage you to try out the new flow titled Explore and create interactive engineering diagrams. This new flow includes a plethora of new functionality and updates such as: Overview of all interactive diagrams in fusion.cognite.com  Easy test setup for relevant file and asset links Handling 1000 engineering diagrams in one go  New P&ID preview component Reducing and cleaning up technical debtAgain, we are still at the experimental stage, so any feedback we receive is beneficial to future iterations and to truly polish the interactive engineering diagrams flow. Please provide any feedback to the Contextualization Cognite hub group found here .

Size limitiations in RAW

I use RAW as a cache system for sensors that come from BACnet (BAS systems) Since it extremly slow.This have worked for some time now, But now CDF would give me a internal server error.. When this error accure, there is no help what so ever on what the problem is.After debugging, It seems i have reached a size cap on a row (5 MB)  but the table have a size cap of about 5 GB (Unconfirmed)So after i included a size check of my data, I chunk it up and spread it out in the rowsAs fare i can see, this limitiations is not mentioned in the docs so here you go, Liberate your data!

Download documents from AssetMeta (Gearbox.js) component.

Hi, does anyone know how I can download files from AssetMeta and / or AssetDocumentsPanel component? Are there other options for retrieving documents related to an asset?

Race conditions on event updates

Hey, To what extent does CDF handle possible race-condition triggering situations like the update of an object from two different systems?The example we are currently considering is whether a disjoint set of metadata on objects (events) can be updated without regard to timing. /Robert

Timeseries aggregates gives strange results for "average"

Aksels ts is Original data , ts average at 04:00 = 0.125, can only be explained by interpolated values The example above shows that 1h aggregates of type average computed at time-point 03:00 takes into considereation the interpolated values in the time-span 03:00 to 04:00. Is it always like this as long as i choose granualarity 1h ? I could not find the answer to my question here:Aggregation | Cognite documentation

Authenticator alternatives

I wonder if it is possible to use alternative authenticator apps to connect to Cognite HUB? I am asking because I’m already using another app for other sites.

Join the frontline of industrial software developmentwelcome

When we founded Cognite four years ago, one of the success criteria we envisioned was that a developer should be able to write a useful industrial application within one hour of being onboarded to Cognite Data Fusion. Coming from the consumer software industry, we did not quite realize how ambitious that was until later. Just think of what it was like to write a mobile phone application 15 years ago. There was no iOS or Android. If you were lucky, you would be writing custom J2ME code for each handset. And there were thousands of different ones, all doing things differently. Fast forward to today, and it is possible for a committed developer to write and distribute a mobile application that runs on most smartphones in the world in a weekend. The industrial world has a similar fragmentation issue that Android and iOS addressed a decade ago. Hundreds of different OT (Operational Technology) systems are present even within a single mid-sized industrial company. They do things slightly dif
