SFTP Server Virtual File System

Is there any way to maintain a virtual file system with SFTP Server? All the data for my files lives in a database. Ideally I would provide a list of files on demand by constructing a list from the database. Then I would dynamically generate those on the fly if the user tries to download one. That way I could keep my sftp server in a lightweight docker container without a persistent storage volume, I could save on monthly storage costs, and from a security perspective I could minimize my attack surface (some files are sensitive). Is there any way to accomplish this with SFTP Server? Perhaps with the ShellCommand event?

Internally we already have such base class named `ISimpleFileSystem`. However we haven't exposed its to the public API yet. We have added that request to our backlog and will consider upgrading our SFTP Server in our next release.
