📑 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
