Infrastructure Setup Summary

Completed Tasks

1. Performance Optimization Configuration Class

File: src/YunDa.Application/YunDa.SOMS.Application.Core/Configuration/PerformanceOptimizationConfig.cs

Created a comprehensive configuration class with the following settings:

Cache Settings: EnableCache, CacheExpiration
Parallelism Settings: MaxDegreeOfParallelism
Batch Settings: BatchSize
Concurrency Settings: MaxConcurrentRequests
Timeout Settings: RequestTimeout
File Validation: MaxFileSize, MaxFilesPerItem, AllowedFileExtensions
Performance Monitoring: EnablePerformanceMonitoring, PerformanceWarningThresholdMs
Retry Settings: EnableRetry, MaxRetryAttempts, RetryBaseDelayMs

All settings have sensible defaults that can be overridden via configuration.

2. Configuration Integration

Modified Files:

src/YunDa.Application/YunDa.SOMS.Application.Core/Configuration/IAppServiceConfiguration.cs
src/YunDa.Application/YunDa.SOMS.Application.Core/Configuration/AppServiceConfiguration.cs

Added PerformanceOptimization property to the application service configuration interface and implementation, making it accessible throughout the application.

3. Configuration Loading Logic

Modified File: src/YunDa.Web/YunDa.SOMS.Web.Core/Configuration/ConfigurationHelper.cs

Added SetPerformanceOptimizationConfig method that:

Loads all performance optimization settings from appsettings.json
Provides fallback to default values if settings are not specified
Supports flexible configuration with optional settings
Uses the prefix "PerformanceOptimization:" for all settings

4. Configuration Documentation

Created File: .kiro/specs/upload-inspection-task-result-performance/configuration-guide.md

Comprehensive documentation including:

Complete configuration example
Detailed description of each setting
Recommendations for different environments (Dev, Staging, Production)
Performance tuning guidelines
Common issues and solutions
Monitoring recommendations

Redis Configuration

The existing Redis configuration infrastructure is already in place:

IRedisConfiguration interface defined
Redis connection settings loaded via ConfigurationHelper.SetRedisConfiguration
Redis repositories registered in ISASRedisModule

No additional Redis configuration changes are needed for this feature.

Dependency Injection

The configuration is automatically available through the existing IAppServiceConfiguration interface, which is already registered in the IoC container. Services can access performance optimization settings via:

public MyService(IAppServiceConfiguration appServiceConfiguration)
{
    var perfConfig = appServiceConfiguration.PerformanceOptimization;
    // Use perfConfig.EnableCache, perfConfig.BatchSize, etc.
}

Next Steps

The infrastructure is now ready for implementing the service components:

CacheService (Task 2)
FileProcessingService (Task 6)
BatchOperationService (Task 4)
PerformanceMonitoringService (Task 7)

Each service can access the configuration through dependency injection and use the settings to control their behavior.

Validation

All configuration files compile successfully with no errors or warnings. The configuration system is ready for use.

Configuration Example for appsettings.json

{
  "PerformanceOptimization": {
    "EnableCache": true,
    "CacheExpirationHours": 1,
    "MaxDegreeOfParallelism": 4,
    "BatchSize": 100,
    "MaxConcurrentRequests": 50,
    "RequestTimeoutSeconds": 30,
    "MaxFileSizeMB": 50,
    "MaxFilesPerItem": 100,
    "AllowedFileExtensions": ".jpg,.jpeg,.png,.bmp,.gif",
    "EnablePerformanceMonitoring": true,
    "PerformanceWarningThresholdMs": 5000,
    "EnableRetry": true,
    "MaxRetryAttempts": 3,
    "RetryBaseDelayMs": 1000
  }
}

Requirements Validation

This implementation satisfies Requirement 4.5:

✅ Performance optimization configuration is configurable
✅ Cache functionality can be enabled/disabled via configuration
✅ All optimization parameters are externalized
✅ Configuration is loaded at application startup
✅ Default values ensure the system works without explicit configuration
