N+1 Query Problem After Cursor ORM Refactoring
After Cursor refactored your ORM queries, page load times increased dramatically. Database logs show hundreds of queries for operations that previously took just a few.
The AI-generated code is fetching related entities one-by-one instead of in batch, causing the classic N+1 problem.
Error Messages You Might See
Query timeout
High database load
Slow response time
Too many queries
Common Causes
- Removed eager loading (include/joins), forcing lazy loading in loops
- Fetching parent objects, then accessing child collections in template/code loop
- Using ORM methods inside loops instead of batch operations
- Relationship configuration changed to lazy-load by default
- Query builder include statement removed during refactoring
How to Fix It
Use eager loading: User.findAll({include: ['Posts', 'Comments']}) or joins. Batch operations outside loops. Use dataloader pattern for GraphQL. Monitor with console.time() around queries and count DB hits.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

How do I detect N+1 problems?
Enable query logging and count queries. N+1 means 1 query + N more. Use DevTools to see query count.
Is it always better to use joins?
Joins are faster but more memory. Sometimes batch separate queries. Test both approaches.
