what are the key points that one should think of while choosing between embeds_many and references_many (or embeds_one and references_one) in Mongoid?
I’m currently preferring embeds_many over references_many, but that is resulting in too many nested embeds_many‘ies and I’m worried that it might add unnecessary overhead to the database.
The most important thing to be aware of is the 4 MB limit for each document in MongoDB – by using references instead of embedding documents, you can keep the size of your documents lower.
