Support for custom File Systems of VSCode

It seems that the data preview currently does not support custom file systems created for VSCode using the (https://code.visualstudio.com/api/extension-guides/virtual-documents, https://github.com/microsoft/vscode-extension-samples/blob/main/fsprovider-sample/README.md)

So I have a custom file system and a file stored on it (e.g. foo://myfolder/myfile.csv). Everything works fine in VSCode itself (opening it from explorer, previewing, etc.) but the extensions does not seem to be able to load that file complaining about that /myfolder/myfile.csv does not exists

Is this supposed to work? if not, any plans to add this feature?

thanks in advance, -gerhard

so the use-case is very similar to what was already discussed in in #298 - it would also be my long-time goal to have everything run also as a web-extension. However, custom file system can also be very beneficial in desktop mode.

So in our extension for Databricks (a big data processing engine in the cloud) the results are stored in Databricks` internal file system called DBFS. I created a custom file system which allows me to “mount” the DBFS into the VSCode explorer https://raw.githubusercontent.com/paiqo/Databricks-VSCode/master/images/FileSystemIntegration.jpg

You would usually do some processing of data on Databricks and view the result files (usually CSV, Parquet, etc.) with a proper data viewer like yours. It would really come in handy to inspect the files from within VSCode directly as accessing them otherwise can be cumbersome

I am also currently in the progress of rewriting everything to workspace.vs as I think it is definitely the way to go for the future and it is actually super powerful!

@gbrueckl I have not decided on that part yet, but if you want to try the latest version of perspective viewer with large csv data files for now, that’s the extension you should try.

I will be adding other Pro sponsors only features to that extension in the months to come. Data preview updates are on hold till I get better sense of how that new viewer is shaping up with embedded analytics db for large data files, streaming data, etc.
