Array vs. Reference Relationship Performance

I'm looking to migrate to Convex from MongoDB. From what I've read in the docs, Convex leans more to the normalized/relational way of storing data. MongoDB is on the totally opposite side and is denormalized with no built-in relationships. Coming from this background I have a question:

If I have a one-to-many relationship, should I put an array of child ids in the parent document, or put a reference to the parent document id in the child document?

The aim of my question is toward performance, not necessarily DX wins/loses. I'm newer to Convex, so feel free to add as much context as you can for the new guy.

Hi @everyone with everything going on today I forgot to post on discord about our EU launch! We have a region in Dublin now! You can start using it immediately, even for folks on the free plan. https://news.convex.dev/we-finally-got-our-eu-visa/ Stay tuned for more regions but also stay tuned for more infra improvements where we improve latency for teams no matter where their servers are located. Just at the tip of the iceberg re all the optimizations we have lined up.
