Frequently Asked Questions

When should you embed documents vs referencing them in MongoDB?
You should **embed** documents (denormalization) when there is a 'contains' relationship (e.g., street address inside a user profile), when the data is queried together, and when the data does not grow unboundedly (fitting within the 16MB document limit). You should **reference** documents (normalization) when the data grows unboundedly (e.g., a post with millions of comments), when the referenced data is frequently updated, or when data is modeled in a many-to-many relationship.
How does 1-on-1 MongoDB mentorship in Tokyo work?
You are matched directly with a Senior MongoDB mentor. Every session is 100% interactive, featuring live pair programming, architectural design, debugging assistance, and interview preparation.
Is the first diagnostic chat free?
Yes. You can chat with your mentor, discuss your blockers or goals, and ensure they are a great fit before committing to paid coaching.
Do you provide on-the-job sprint support?
Yes! If you are currently working on a production project and need confidential, senior guidance on tricky bugs or architecture, we offer flexible job support packages.
