+# Tenant Settings REST API Documentation
+
+## Overview
+The Tenant Settings API provides endpoints for managing configuration settings specific to individual tenants in the KonfDB multi-tenant configuration service. Each tenant (suite) can have its own isolated set of configuration parameters with default values and metadata.
+
+## Base URL
+```
+http://{server}:{port}/api/CommandService/
+```
+
+## Authentication
+All endpoints require authentication via a token passed in the request header or query parameter.
+
+## Endpoints
+
+### 1. Get Tenant Settings
+Retrieves all configuration settings for a specific tenant.

+
+### 4. Update Single Tenant Setting
+Updates a specific configuration setting for a tenant.
+
+**Endpoint:** `PUT /tenants/{tenantId}/settings/{key}`
+
+**Parameters:**
+- `tenantId` (path, required): The numeric ID of the tenant/suite
+- `key` (path, required): The setting key to update

+
+**Request Body:**
+```json
+"newValue"
+```
+
+**Response:**

+ -H "Authorization: Bearer {token}" \
+ -H "Content-Type: application/json" \
+ -d '200'
+```
+
+## Error Handling
+
+All endpoints return error responses in the following format:
+
+```json
+{
+ "error": "Error message",
+ "statusCode": 400
+}
+```
+
+Common error scenarios:
+- **Invalid Tenant ID**: Returns 400 Bad Request
+- **Non-existent Tenant**: Returns 404 Not Found
+- **Missing Required Parameters**: Returns 400 Bad Request
+- **Tenant ID Mismatch**: Returns 400 Bad Request (when URL tenant ID doesn't match body tenant ID)
+- **Server Errors**: Returns 500 Internal Server Error
+
+## Multi-Tenant Isolation
+
+The API ensures complete isolation between tenants:
+- Settings for one tenant cannot be accessed or modified by another tenant
+- Each tenant has its own namespace for configuration keys
+- Default values can be tenant-specific
+- Audit trails are maintained per tenant
+
+## Best Practices
+
+1. **Use Merged Settings**: When retrieving settings, the API merges actual settings with default values. This ensures all expected keys are present.
+
+2. **Validate Tenant ID**: Always validate that the tenant ID is numeric before making API calls.
+
+3. **Handle Missing Keys**: When retrieving a single setting, handle the 404 case gracefully as the key might not exist.
+
+4. **Batch Updates**: When updating multiple settings, use the bulk update endpoint rather than multiple single-key updates for better performance.
+
+5. **Version Management**: Use the metadata version field to track configuration schema changes.
+
+## Command Line Examples
+
+### Using the KonfDB Command Line Interface:
+
+```bash
+# Get all settings for tenant 1
+konfdbc GetTenantSettings /tenantId=1
+
+# Through the generic Execute command
+konfdbc Execute "GetTenantSettings /tenantId=1"
+```
+
+## Integration with Existing KonfDB Features
+
+The Tenant Settings API integrates seamlessly with existing KonfDB features:
+- **Audit Logging**: All operations are logged in the audit trail
+- **Encryption**: Sensitive settings can be encrypted using KonfDB's encryption features
+- **Caching**: Settings are cached for performance
+- **Role-Based Access**: Access is controlled based on user roles (Admin, ReadOnly)
+
+## Migration Guide
+
+For existing KonfDB users migrating to use tenant-specific settings:
+
+1. Identify suite-specific parameters currently stored as regular parameters
+2. Use the bulk update endpoint to migrate these to tenant settings
+3. Update client applications to use the new endpoints
+4. Remove old parameter mappings once migration is complete
+
+## Performance Considerations
+
+- Settings are cached in memory for fast retrieval
+- Bulk operations are optimized for database performance
+- Default values are computed once and cached
+- Metadata is updated asynchronously to avoid blocking operations

+ - Added methods: GetTenantSettings, UpdateTenantSettings, DeleteTenantSettings
+
+2. **Data Store Implementation**
+ - `/Server/KonfDB.Engine/Database/Stores/ConfigurationDataStore.cs`
+ - Implemented tenant settings data access methods
+
+## Features Implemented
+
+### 1. REST API Endpoints
+
+#### GET /tenants/{tenantId}/settings
+- Retrieves all configuration settings for a specific tenant
+- Returns settings with default values for missing keys
+- Includes metadata (created date, modified date, version, etc.)
+
+#### PUT /tenants/{tenantId}/settings
+- Updates all settings for a specific tenant
+- Validates tenant ID consistency
+- Updates metadata automatically
+
+#### GET /tenants/{tenantId}/settings/{key}
+- Retrieves a specific setting value for a tenant
+- Returns merged value (actual or default)
+
+#### PUT /tenants/{tenantId}/settings/{key}
+- Updates a specific setting value for a tenant
+- Creates the setting if it doesn't exist
+
+### 2. Data Model
+
+**TenantSettingsModel** includes:
+- `TenantId`: Unique identifier for the tenant
+- `TenantName`: Human-readable tenant name
+- `IsActive`: Tenant active status
+- `Settings`: Dictionary of actual configuration values
+- `DefaultValues`: Dictionary of default values
+- `Metadata`: Creation/modification timestamps and version info
+
+### 3. Multi-Tenant Isolation
+
+- Complete isolation between tenants
+- Settings for one tenant cannot be accessed by another
+- Each tenant has its own configuration namespace
+- Audit trails maintained per tenant
+
+### 4. Error Handling
+
+Comprehensive error handling for:
+- Invalid tenant IDs (non-numeric, null, empty)
+- Non-existent tenants (404 Not Found)
+- Invalid request data (400 Bad Request)
+- Tenant ID mismatches
+- Server errors (500 Internal Server Error)
+
+### 5. Testing
+
+**Unit Tests** cover:
+- Valid tenant ID scenarios
+- Invalid input validation
+- Null/empty parameter handling
+- Settings merge functionality
+
+**Integration Tests** cover:
+- End-to-end REST API flow
+- Multi-tenant isolation verification
+- Single and bulk operations
+- Error scenarios
+
+## How to Use
+
+### 1. Via REST API
+
+```bash
+# Get all settings for tenant 1
+curl -X GET "http://localhost:8080/api/CommandService/tenants/1/settings" \
+ -H "Authorization: Bearer {token}"
+
+# Update settings for tenant 1
+curl -X PUT "http://localhost:8080/api/CommandService/tenants/1/settings" \
+ -H "Authorization: Bearer {token}" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "tenantId": 1,
+ "settings": {
+ "maxConnections": 200,
+ "timeout": 60
+ }
+ }'
+```
+
+### 2. Via Command Line
+
+```bash
+# Using KonfDB command line interface
+konfdbc GetTenantSettings /tenantId=1
+```
+
+### 3. Via Code
+
+```csharp
+// Using the service directly
+var tenantService = new TenantService();
+var settings = tenantService.GetTenantSettings("1");
+
+// Using the command pattern
+var command = new GetTenantSettings();
+var input = new CommandInput { ["tenantId"] = "1" };
+var output = command.OnExecute(input);
+```
+
+## Database Schema
+
+The implementation uses existing KonfDB tables:
+- `Suites`: Represents tenants
+- `Parameters`: Stores configuration key-value pairs
+- `Mappings`: Links parameters to suites
+
+No database schema changes are required.
+
+## Security Considerations
+
+1. **Authentication**: All endpoints require valid authentication tokens
+2. **Authorization**: Access controlled by user roles (Admin, ReadOnly)
+3. **Input Validation**: All inputs are validated and sanitized
+4. **Tenant Isolation**: Enforced at the data access layer
+
+## Performance Optimizations
+
+1. **Caching**: Settings are cached for fast retrieval
+2. **Bulk Operations**: Optimized for database performance
+3. **Lazy Loading**: Metadata computed only when needed
+4. **Connection Pooling**: Efficient database connection management
+
+## Future Enhancements
+
+Potential improvements for future versions:
+1. Setting versioning and rollback capabilities
+2. Setting inheritance between environments
+3. Real-time setting updates via WebSockets
+4. Setting validation rules and schemas
+5. Bulk import/export functionality
+6. Setting change notifications
+
+## Troubleshooting
+
+### Common Issues:
+
+1. **404 Not Found**: Verify the tenant ID exists in the database
+2. **400 Bad Request**: Check that tenant ID is numeric
+3. **500 Server Error**: Check database connectivity and logs
+4. **Authentication Failed**: Ensure valid token is provided
+
+### Logging:
+
+All operations are logged with:
+- Request/response details
+- Error stack traces
+- Performance metrics
+- Audit trail entries
+
+## Deployment
+
+1. Build the solution to compile new files
+2. Deploy updated assemblies to server
+3. Restart KonfDB service
+4. Verify endpoints are accessible
+5. Run integration tests to confirm deployment
+
+## Backward Compatibility
+
+This feature is fully backward compatible:
+- No breaking changes to existing APIs
+- No database schema modifications
+- Existing functionality remains unchanged
+- New endpoints are additive only
+
+## Support
+
+For issues or questions:
+- Check API documentation
+- Review test cases for usage examples
+- Consult KonfDB documentation at http://www.konfdb.com
+- Submit issues on the project repository
