-- Integration tests should verify Redis cluster connectivity

 - **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
