Implementation Guides
Documentation of major implementations and architectural decisions.
Version 4+ Implementation
Major refactoring in v4.202602 focused on performance and reliability.
Startup Performance Optimization
Problem: Initial startup took 2.2 seconds due to loading all commands upfront.
Solution: Lazy-load commands only when needed.
Result: ~7x faster startup (700ms).
Details in: OPTIMIZATION_PATTERN.md
Command Consistency
Problem: Commands had inconsistent naming and parameters.
Solution: Standardized all commands across the CLI.
Changes Tracked In:
Parameter Standardization
Effort: Standardized parameter naming and behavior.
For details, see: PARAMETER_STANDARDIZATION_PLAN.md
Key Changes:
- Consistent schema/source naming
- Consistent table/target naming
- Consistent output format options
- Unified error handling
Feature Implementations
Internationalization (i18n)
Multi-language support for all output and help text.
Details: INTERNATIONALIZATION_UPDATES.md
Supported Languages:
- English (en)
- German (de)
Implementation:
- Properties files in
_i18n/ - Dynamic loading based on locale
- Fallback to English if translation missing
Model Context Protocol (MCP)
AI-first integration enabling natural language commands.
Details: MCP_SERVER_IMPLEMENTATION_COMPLETE.md
Architecture:
- Standalone Node.js MCP server
- Exposes HANA CLI tools
- Provides database introspection
- Enables Claude/AI integration
API Server Mode
REST API server for programmatic access.
Features:
- HTTP endpoints for all commands

Testing & Coverage
Testing infrastructure and metrics.
Details:
Focus Areas:
- Unit test coverage
- Integration test coverage
- Benchmark tests
- Performance profiling
Architecture Decisions
Why Commands Are Lazy-Loaded
Trade-off: Slightly slower first command execution vs. instant CLI startup
Decision: Lazy-load for better UX (faster initial response to --help, --version, etc.)
Why MCP Server Is Separate
Trade-off: Additional process to manage vs. simplified main CLI
Decision: Separate process allows independent scaling and updates
Why REST API Is Built-In
Trade-off: More code in CLI vs. ability to script and integrate
Decision: Built-in REST API for easier scripting and integration
Migration & Upgrade Path
Version upgrade considerations documented in:
Backward Compatibility:
- Command names maintained across versions
- Aliases for deprecated commands
- Deprecation warnings before removal
- Migration guides for breaking changes
Future Roadmap
Planned implementations:
- Additional language support
- Advanced query builder
- Real-time monitoring
- Mobile app integration
- GraphQL API option
