I think option A could work too, as it keeps everything in one document for each user.

Hah, option D? What is this, a joke? Creating a root collection for posts and then subcollections for profiles? That's just asking for trouble!

I'm not sure about that. Wouldn't it be easier to just store the posts as a nested list in the user profile? Option A seems simpler to me.

I think option C is the way to go. Separating user profiles and posts into different collections makes it easier to manage and scale the data.

Option C sounds good, it allows for easy access to user profiles and their corresponding posts.

I think option B might be better, it keeps user profiles and posts in separate collections but at the same level.
