I’m surprised they’re not using a more relational approach with MySQL.

Wait, why would you create a subcollection for profiles? That seems odd.

I practiced a similar question, and I think nesting posts within user profiles might complicate queries. So, option C seems like the best choice.

I'm not entirely sure, but I feel like having a separate collection for posts could lead to better performance. Maybe option B?

I feel pretty confident about this one. Based on the information provided, I think option C is the best approach - creating one root collection for user profiles and a subcollection for each user's posts. This will allow us to easily query and access the data we need.

Okay, let's think this through step-by-step. We want to store user profiles and user posts, and the question is asking about the Firestore collection design. I'd start by considering how the data will be accessed and queried.

Hmm, I'm a bit unsure about this one. I know Firestore has different ways to model data, but I'm not sure which approach would be best here. I'll need to carefully consider the tradeoffs between the options.

Option C is the way to go, no doubt. Keeping those user posts nice and cozy in their own subcollections - it's like a Firestore hug for your data!

I see your point, Antione, but I think option D could also work well by organizing posts first and then linking them to user profiles.

I'm going to have to go with option C. Nested subcollections just make sense for this use case, and it aligns with best practices for Firestore data modeling.
