§Generic Configuration Manager

This module provides a generic, reusable configuration management system for the adaptive pipeline system. It supports validation, versioning, migration, and hot-reloading of configuration data.

§Overview

The generic configuration manager provides:

  • Type-Safe Configuration: Generic configuration management for any type
  • Validation: Comprehensive validation with detailed error reporting
  • Versioning: Configuration schema versioning and migration support
  • Hot Reloading: Runtime configuration updates without restart
  • Thread Safety: Safe concurrent access to configuration data

§Architecture

The configuration manager follows generic design patterns:

  • Generic Design: Works with any configuration type implementing required traits
  • Validation Framework: Pluggable validation with detailed error reporting
  • Migration System: Automatic migration between configuration versions
  • Event System: Configuration change notifications and observers

§Key Features

§Configuration Validation

  • Schema Validation: Validate configuration against defined schemas
  • Business Rules: Enforce business logic and constraints
  • Error Reporting: Detailed error messages with field-level information
  • Warning System: Non-fatal warnings for configuration issues

§Version Management

  • Schema Versioning: Track configuration schema versions
  • Migration Support: Automatic migration between versions
  • Backward Compatibility: Support for older configuration formats
  • Version Detection: Automatic detection of configuration versions

§Hot Reloading

  • Runtime Updates: Update configuration without application restart
  • Change Detection: Detect configuration file changes
  • Atomic Updates: Atomic configuration updates to prevent inconsistency
  • Rollback Support: Rollback to previous configuration on errors

§Usage Examples

§Basic Configuration Management

§Configuration with Hot Reloading

§Configuration Migration

§Validation Framework

§Validation Results

The validation system provides detailed feedback:

  • Errors: Critical validation failures that prevent usage
  • Warnings: Non-critical issues that should be addressed
  • Field-Level Information: Specific field names and error contexts
  • Severity Levels: Different severity levels for different issues

§Custom Validation Rules

  • Business Logic: Implement custom business logic validation
  • Cross-Field Validation: Validate relationships between fields
  • External Validation: Validate against external resources
  • Conditional Validation: Conditional validation based on other fields

§Migration System

§Migration Strategies

  • Automatic Migration: Automatic migration between compatible versions
  • Manual Migration: Manual migration for complex changes
  • Incremental Migration: Step-by-step migration through versions
  • Rollback Support: Rollback to previous versions on failure

§Version Compatibility

  • Semantic Versioning: Use semantic versioning for schema versions
  • Compatibility Matrix: Define compatibility between versions
  • Breaking Changes: Handle breaking changes gracefully
  • Deprecation Warnings: Warn about deprecated configuration options

§Performance Considerations

§Memory Usage

  • Efficient Storage: Efficient storage of configuration data
  • Lazy Loading: Lazy loading of configuration sections
  • Memory Pooling: Reuse configuration objects when possible

§Access Performance

  • Caching: Cache frequently accessed configuration values
  • Read Optimization: Optimize for frequent read operations
  • Lock Contention: Minimize lock contention for concurrent access

§Error Handling

§Configuration Errors

  • Parse Errors: Handle configuration file parsing errors
  • Validation Errors: Comprehensive validation error reporting
  • Migration Errors: Handle migration failures gracefully
  • File System Errors: Handle file system access errors

§Recovery Strategies

  • Default Values: Use default values for missing configuration
  • Fallback Configuration: Fallback to previous valid configuration
  • Error Reporting: Detailed error reporting with suggestions
  • Graceful Degradation: Continue operation with reduced functionality

§Integration

The configuration manager integrates with:

  • File System: Load configuration from various file formats
  • Environment Variables: Override configuration with environment variables
  • Command Line: Override configuration with command line arguments
  • External Services: Load configuration from external configuration services

§Thread Safety

The configuration manager is fully thread-safe:

  • Concurrent Access: Safe concurrent access to configuration data
  • Atomic Updates: Atomic configuration updates
  • Lock-Free Reads: Lock-free reads for better performance

§Future Enhancements

Planned enhancements include:

  • Configuration UI: Web-based configuration management interface
  • A/B Testing: Support for A/B testing of configuration changes
  • Configuration Validation Service: External validation service integration
  • Configuration Analytics: Analytics and monitoring of configuration usage
