Given that they index over 8 billion pages, and likely have hundreds of billions of records in their databases, I'd think dealing with hundreds of thousands of records would be fairly easy in comparison.
Besides, there's no reason to have all of the domains in one table, or even database.
Also don't forget that if they are tracking the click throughs, they've already got those domains in a database. So I'd still say it borders on trivial! :)
