Is this really the goal your professor gave you? Unless this is for one or two corporate domains, considered to be a bad practice in general. That being said, if the records come from a MySQL database, you'll need to query the database from Lua in a preresolve() hook OR (much better solution) you'll need multiple components. Crucial in that last solution is that the resolver (or dnsdist, as that might make things easier) knows which domains are "local" and thus need to be send to PowerDNS Auth, and which aren't, and need to be sent to Google. But please, reread paragraph 1. Also check with your professor if you've correctly understood the assignment, as this sounds like a bad practice.
