Wait, are we really saying "always"? That sounds risky!

I think the answer is definitely not always or never, but I can't remember the exact scenarios for embedded collections.

I feel like the answer could be option A, but I also recall something about performance issues with large datasets.

I remember practicing a question where it mentioned that large collections might be better off in separate collections, so I’m leaning towards option B.

I think we should use an embedded collection when the many is not very large, but I'm not entirely sure if there's a specific limit.

Ah, I remember learning about this in class. The general rule is to use embedded collections when the "many" side isn't too big. Separate collections are better for larger data sets.

Ah, I see. So it's all about balancing performance and flexibility. Embedded collections are more efficient, but separate collections give you more control. Gotta weigh the options.

Hmm, I'm a bit unsure about this. I know embedded collections can be more efficient, but when should we really use them over separate collections?

This is a tricky one. I'll need to think carefully about the trade-offs between embedded collections and separate collections.

Okay, I think I've got this. The key is considering the size of the "many" side of the relationship. If it's not very large, embedded collections are probably the way to go.

Hmm, this is a tricky one. I'm not entirely sure where to start, but I think I'll begin by verifying the tunnel protection is applied correctly. That could be the root cause of the "MM_NO_STATE" error.

I'm just imagining a database with a 'many' field the size of the Library of Congress. Talk about a document weight-lifting challenge!

Definitely B. If the many is very large, embedding it just sounds like a recipe for a bloated document. Separate collections are the way to go.
