Transfer Using Streams

Is there anyway to transfer files using streams instead of having to saving the file to an HDD first. I would like to be able to get a file from a remote SFTP server, then insert the data into a database, then save or destroy it.

Thank you in advance.

No, this is not supported. You have to save the contents to a temporary file.

This has been implemented for SFTP:
