Sign DBFS file URLs

Is it possible to sign DBFS file URLs via the service principal for temporary public access?

What I actually want to do is to have integration with Databricks in my app platform. For that purpose, I need to sign DBFS file URLs from my platform (ec2) for public temporary access. I think to do it via the service principal. I have no idea whether it is possible, or is it possible via Delta Lake?

Signing a file is generally related to what is done by the underlying cloud storage. However, there might be better ways of doing this depending on what you want to share.

If you want to share structured data you can save it as a Delta table in the Metastore and share it using SQL Execution API or JDBC. You can also use Delta Sharing for this which will use Signed URLs underneath.
Another functionality for Delta Sharing is to share Notebook files between Databricks workspaces and it could expand later to include other types of files as well.
