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.
