Storage context for Jupyter Notebooks

Hi!

What is the active context for the server side stored Jupyter Notebooks?

If I’m working on two different CDF projects, I still see the same notebooks in both of them.

Hi,

Thanks for using the Jupyter notebook service. If you look in the Quickstart Guide notebook in Jupyter notebook, and the documentation you will see mentioning of “stored locally” and “stored in your browser”. So notebooks that are not stored within the Notebooks folder (and in one of the data set folders in there, see docs), are stored in your web browser IndexedDB storage. This storage is across CDF projects, and is a useful feature when you are working on scripts across projects.

There is a way for us to change so they are scoped to per CDF project, but that would be a breaking change that removes the usefulness we currently see with the sharing across projects. The local notebooks are only visible to you and no other users in those CDF projects.

Hope this helps!

Thanks for the clarification. It may be something in the documentation regarding this, but the webapp only states “Stored in Cognite Data Fusion”, which is a bit unambiguous. From my point of view, if this is shared personally across projects, maybe that needs to be clearer in the UI? I (personally) see it as more useful to send references to notebooks to other project members, rather than sharing my own notes across projects (most data references would differ anyway). Still, adding the project scope doesn’t need to be a breaking change, but you would have to add another option in the notebook browser - browser, personal and project :)

Thanks for the feedback! So Stored in Cognite Data Fusion means they are actually stored in CDF, accessible for anyone with access to those data sets. Stored in browser is only for you, locally.

So this means, if you leverage the Notebooks folder (you have to use one of the existing data set folders in there, you can’t create new ones unfortunately), others can use the notebooks. So you do have the personal and project storage as you want!
