How can I compile part/full of my DB on your server into 1 file?

Now: I take table with info about all tables in db and then I take all tables from db and save them on device. I spend on it 3 sec.
Dream: But if I could compile my db’s tables into 1 file .db, I could spent about 0,05 sec on this operation. I could keep this file in Backenless storage and get it and then I could copy it on device.
How can I compile DB into 1 file with your api/console/etc?

I did it with mobile app. Can I put some code somewhere in Backendless console so I can do it without second app/site/etc?

You can create a service in Business Logic which will do it via a request.
