### 📑 Index Optimization
|
|
|
|
**Recently Created Indexes (6 new):**
|
|
- ✅ `idx_contacts_status` - Contact message filtering
|
|
- ✅ `idx_contacts_created_at` - Contact sorting by date
|
|
- ✅ `idx_inventory_logs_action` - Inventory action filtering
|
|
- ✅ `idx_service_images_service_id` - Service image lookups
|
|
- ✅ `idx_service_images_display_order` - Image ordering
|
|
- ✅ `idx_order_status_history_created_at` - Status history sorting
|
|
|
|
**Existing Optimized Indexes:**
|
|
|
|
**Products Table (9 indexes):**
|
|
- Primary key, category, active status, stock levels, low stock alerts
|
|
- Composite indexes for category+active filtering
|
|
|
|
**Services Table (7 indexes):**
|
|
- Primary key, category, active status, created date
|
|
- Composite indexes for category+active filtering
|
|
|
|
**Orders Table (6 indexes):**
|
|
- Primary key, user, status, created/updated dates
|
|
- Composite index for user+status queries
|
|
|
|
**Users Table (2 indexes):**
|
|
- Primary key, email (unique)
|
|
|
|
**Reviews, Bookings, Cart Items, Order Items:** All properly indexed
|
|
|
|
### 🎯 Query Performance Optimizations
|
|
|
|
1. **Eager Loading Configured:**
|
|
- Products load with images using `selectinload(Product.images)`
|
|
- Services load with images using `selectinload(Service.images)`
|
|
- Cart items preload product details
|
|
- Orders preload items and status history
|
|
- Reviews preload user information
|
|
|
|
2. **Index Coverage:**
|
|
- All frequently queried columns indexed
|
|
- Foreign keys all indexed for JOIN performance
|
|
- Date fields indexed for sorting
|
|
- Status fields indexed for filtering
|
|
|
|
3. **Relationship Optimization:**
|
|
- Cascade deletes configured where appropriate
|
|
- Orphan deletion enabled for dependent records
|
|
- Proper lazy/eager loading balance
|
|
|
|
### 🔧 Backend Alignment
|
|
|
|
**Models Match Database Schema:** ✅
|
|
- All model definitions align with database structure
|
|
- All relationships properly configured
|
|
- Cascade rules correctly implemented
|
|
|
|
**Query Patterns Optimized:** ✅
|
|
- Admin endpoints use eager loading for images
|
|
- Public endpoints cache-friendly
|
|
- No N+1 query issues
|
|
- Proper use of `selectinload` for relationships
|
|
|
|
