No N+1 Waterfall Queries in Server Components or Endpoints
Agents execute database queries in array.map(async (item) => await db.find(item.id)) loops rather than using single batch queries.
1-Click Fix Prompt for Cursor & Claude Code
Review my codebase for "No N+1 Waterfall Queries in Server Components or Endpoints" (PERF-004). Issue: Agents execute database queries in array.map(async (item) => await db.find(item.id)) loops rather than using single batch queries. Remediation required: Batch database queries using WHERE id IN (...) or use ORM include/join features to fetch relational data in one roundtrip. Please: 1. Locate any occurrences of this issue across my repository. 2. Refactor the code to follow production standards without breaking existing functionality. 3. Provide a clear command or step to test and verify the fix.
Why AI Assistants Write This Bug
Agents execute database queries in array.map(async (item) => await db.find(item.id)) loops rather than using single batch queries.
AI code generation prioritizes immediate syntax execution over production edge cases. When an assistant hits an undefined variable or strict type error, it frequently takes the path of least resistance rather than implementing standard pre-launch security patterns.
