### Testing Approach
- Unit tests exist for core services (FlashSaleServiceTest, RedisServiceTest)
- Integration tests should verify Redis cluster connectivity
- Load testing recommended for flash sale scenarios
- Unit tests should be created for core services (FlashSaleService, RedisService, CartService)
- Integration tests should verify Redis cluster connectivity and database operations
- Load testing recommended for flash sale scenarios to validate concurrency handling

- **Actuator Endpoints**: /actuator/health, /actuator/metrics, /actuator/prometheus
- **Log Files**: logs/flash-sale-system.log with detailed Redis and SQL logging
- **Debug Level**: Enabled for package com.org.flashsalesystem and Redis operations
## Security Considerations
- **Redis Authentication**: Cluster uses password authentication as configured in application.yml
- **Database Connection**: Uses HikariCP with connection pooling and timeout configurations
- **Password Encoding**: Spring Security crypto for password hashing
- **Rate Limiting**: Built-in rate limiting to prevent abuse of flash sale endpoints
