What are the differences between embedding and referencing in MongoDB schema design?

In MongoDB, embedding means storing related data in the same document, while referencing involves linking documents through IDs.

Can you give me an example of when to use embedding?

Sure! Use embedding when you have data that is frequently accessed together, like a blog post and its comments.

And when should I use referencing instead?

Referencing is ideal when you have large datasets or when the related data is not always needed, like users and their profiles.

What are the performance implications of each approach?

Embedding can improve read performance but may increase document size, while referencing can lead to more queries but keeps documents smaller.
