# Change: Optimize Database Query Performance

## Why

QA review identified N+1 query patterns in project member listing and related endpoints. When loading a project with many members, each member triggers a separate database query, causing significant performance degradation.

## What Changes

- Implement eager loading (joinedload) for project member relationships
- Add query batching for related entity loading
- Add database query logging in development mode for detection

## Impact

- Affected specs: `resource-management`
- Affected code:
  - `backend/app/services/project_service.py` - Member loading
  - `backend/app/api/v1/endpoints/projects.py` - Query optimization
  - `backend/app/models/` - Relationship configurations
