- MongoDB's flexibility initially led to clunky queries and poor performance due to relational database habits.
- Data modeling mistakes included over-referencing and then over-embedding, leading to performance and consistency issues.
- Understanding when to embed vs. reference data is crucial, guided by access patterns and update frequency.
- Indexing requires matching query patterns; indiscriminate indexing doesn't improve performance.
- Learning to read explain() plans and using the aggregation framework significantly improved query efficiency.
- Proper monitoring and alerting shifted the approach from reactive to proactive problem-solving.
- Reliability involves understanding failover, recovery plans, and cluster behavior under failure.
- Solid fundamentals allow exploration of advanced features like Atlas Search and Vector Search without risking stability.
- Key advice: prioritize data modeling, learn indexing and aggregation, monitor early, and utilize MongoDB's educational resources.
- MongoDB Skill Badges offer practical, focused learning to overcome common challenges efficiently.
