Exactly, Latrice. It's important to choose the option that is optimized for large volumes of data.

I agree with Mari. Using queryLocator method is specifically designed for retrieving large data volumes efficiently.

But wouldn't option A, creating a formula field and filtering based on it, also help improve performance?

I believe option D, using the Database queryLocator method, would be the best choice here.

I personally think option B) could also work by breaking down the query into two parts and joining the result sets.

Haha, the @Future annotation in Option C? That's like trying to put a bandaid on a broken leg. Definitely not the way to go here.

I agree with Yen, combining fields with a formula field seems like a good approach to optimize the query.

Option B is interesting, but I'm not sure if the additional join operation would be faster than just using queryLocator. Hmm, tough choice.

I'm not a fan of the formula field idea in Option A. That seems like a hack and could get messy. I'd go with the queryLocator method.
