# Configuration Management

## Overview
The Configuration Management service will provide centralized management of application and service configurations across the stock-bot platform. It will handle environment-specific settings, dynamic configuration updates, secrets management, and configuration versioning to ensure consistent and secure system configuration.

## Planned Features

### Configuration Storage
- **Hierarchical Configuration**: Nested configuration structure
- **Environment Separation**: Environment-specific configurations
- **Schema Validation**: Configuration format validation
- **Default Values**: Fallback configuration defaults
- **Configuration as Code**: Version-controlled configuration

### Dynamic Configuration
- **Runtime Updates**: Changes without service restart
- **Configuration Propagation**: Real-time distribution of changes
- **Subscription Model**: Configuration change notifications
- **Batch Updates**: Atomic multi-value changes
- **Feature Flags**: Dynamic feature enablement

### Secrets Management
- **Secure Storage**: Encrypted storage of sensitive values
- **Access Control**: Fine-grained access to secrets
- **Secret Versioning**: Historical versions of secrets
- **Automatic Rotation**: Scheduled credential rotation
- **Key Management**: Management of encryption keys

### Operational Features
- **Configuration History**: Tracking of configuration changes
- **Rollbacks**: Revert to previous configurations
- **Audit Trail**: Comprehensive change logging
- **Configuration Comparison**: Diff between configurations
- **Import/Export**: Bulk configuration operations

## Planned Integration Points

### Service Integration
- All platform microservices
- CI/CD pipelines
- Infrastructure components
- Development environments

### External Systems
- Secret management services
- Source control systems
- Operational monitoring
- Compliance systems

## Planned Technical Implementation

### Technology Stack
- **Configuration Server**: Spring Cloud Config or custom solution
- **Secret Store**: HashiCorp Vault or AWS Secrets Manager
- **Storage**: Git-backed or database storage
- **API**: RESTful interface with versioning
- **SDK**: Client libraries for service integration

### Architecture Pattern
- Configuration as a service
- Event-driven configuration updates
- Layered access control model
- High-availability design

## Development Guidelines

### Configuration Structure
- Naming conventions
- Hierarchy organization
- Type validation
- Documentation requirements

### Secret Management
- Secret classification
- Rotation requirements
- Access request process
- Emergency access procedures

### Integration Approach
- Client library usage
- Caching recommendations
- Failure handling
- Update processing

## Implementation Roadmap
1. Static configuration management
2. Basic secrets storage
3. Dynamic configuration updates
4. Advanced secret management features
5. Operational tooling and integration
