🚀 System Capabilities (Complete)

1. Individual Service Deletion

Every service can independently delete its tenant data:

DELETE http://{service}:8000/api/v1/{service}/tenant/{tenant_id}

2. Deletion Preview (Dry-Run)

Every service provides preview without deleting:

GET http://{service}:8000/api/v1/{service}/tenant/{tenant_id}/deletion-preview

3. Orchestrated Deletion

The orchestrator can delete across ALL 12 services in parallel:

orchestrator = DeletionOrchestrator(auth_token)
job = await orchestrator.orchestrate_tenant_deletion(tenant_id)
# Deletes from all 12 services concurrently

4. Tenant Business Rules

  • Admin verification before deletion
  • Ownership transfer support
  • Permission checks
  • Event publishing (tenant.deleted)

5. Complete Logging & Error Handling

  • Structured logging with structlog
  • Per-step logging for audit trails
  • Comprehensive error tracking
  • Transaction management with rollback

6. Security

  • Service-only access control
  • JWT token authentication
  • Permission validation
  • Audit log creation

🔧 Architecture Highlights

Standardized Pattern

All 12 services follow the same pattern:

  1. Deletion Service Class

    class {Service}TenantDeletionService(BaseTenantDataDeletionService):
        async def get_tenant_data_preview(tenant_id) -> Dict[str, int]
        async def delete_tenant_data(tenant_id) -> TenantDataDeletionResult
    
  2. API Endpoints

    @router.delete("/tenant/{tenant_id}")
    @service_only_access
    async def delete_tenant_data(...)
    
    @router.get("/tenant/{tenant_id}/deletion-preview")
    @service_only_access
    async def preview_tenant_data_deletion(...)
    
  3. Deletion Order

    • Delete children before parents (foreign keys)
    • Track all deletions with counts
    • Log every step
    • Commit transaction atomically

Result Format

Every service returns the same structure:

{
    "tenant_id": "abc-123",
    "service_name": "training",
    "success": true,
    "deleted_counts": {
        "trained_models": 45,
        "model_artifacts": 90,
        "model_training_logs": 234,
        ...
    },
    "errors": [],
    "timestamp": "2025-10-31T12:34:56Z"
}

🎓 Special Considerations by Service

Services with Shared Data

  • External Service: Preserves city-wide weather/traffic data (shared across tenants)
  • Notification Service: Preserves system templates (is_system=True)

Services with Physical Files

  • Training Service: Physical model files (.pkl, metadata) should be cleaned separately
  • POS Service: Webhook payloads and logs may be archived

Services with CASCADE Deletes

  • All services properly handle foreign key cascades
  • Children deleted before parents
  • Explicit deletion for proper count tracking

📊 Expected Deletion Volumes

Service Typical Records Time to Delete
Orders 10,000-50,000 2-5 seconds
Inventory 1,000-5,000 <1 second
Recipes 100-500 <1 second
Sales 20,000-100,000 3-8 seconds
Production 2,000-10,000 1-3 seconds
Suppliers 500-2,000 <1 second
POS 50,000-200,000 5-15 seconds
External 100-1,000 <1 second
Forecasting 10,000-50,000 2-5 seconds
Training 100-1,000 1-2 seconds
Alert Processor 5,000-25,000 1-3 seconds
Notification 10,000-50,000 2-5 seconds
TOTAL 100K-500K 20-60 seconds

Note: Times for parallel execution via orchestrator
