# Demo Session Service - Modern Architecture
|
||||
|
||||
## 🚀 Overview
|
||||
|
||||
The **Demo Session Service** has been fully modernized to use a **direct database loading approach with shared utilities**, eliminating the need for Kubernetes Jobs and HTTP-based cloning. This new architecture provides **instant demo creation (5-15s)**, **deterministic data**, and **simplified maintenance**.
|
||||
|
||||
## 🎯 Key Improvements
|
||||
|
||||
### Previous Architecture ❌
|
||||
```mermaid
|
||||
graph LR
|
||||
Tilt --> 30+KubernetesJobs
|
||||
KubernetesJobs --> HTTP[HTTP POST Requests]
|
||||
HTTP --> Services[11 Service Endpoints]
|
||||
Services --> Databases[11 Service Databases]
|
||||
```
|
||||
- **30+ separate Kubernetes Jobs** - Complex dependency management
|
||||
- **HTTP-based loading** - Network overhead, slow performance
|
||||
- **Manual ID mapping** - Error-prone, hard to maintain
|
||||
- **30-40 second load time** - Poor user experience
|
||||
|
||||
### Current Architecture ✅
|
||||
```mermaid
|
||||
graph LR
|
||||
DemoAPI[Demo Session API] --> DirectDB[Direct Database Load]
|
||||
DirectDB --> SharedUtils[Shared Utilities]
|
||||
SharedUtils --> IDTransform[XOR ID Transform]
|
||||
SharedUtils --> DateAdjust[Temporal Adjustment]
|
||||
SharedUtils --> SeedData[JSON Seed Data]
|
||||
DirectDB --> Services[11 Service Databases]
|
||||
```
|
||||
- **Direct database loading** - No HTTP overhead
|
||||
- **XOR-based ID transformation** - Deterministic and consistent
|
||||
- **Temporal determinism** - Dates adjusted to session creation time
|
||||
- **5-15 second load time** - 60-70% performance improvement
|
||||
- **Shared utilities** - Reusable across all services
|
||||
|
||||
## 📊 Performance Metrics
|
||||
|
||||
| Metric | Previous | Current | Improvement |
|
||||
|--------|--------|--------|-------------|
|
||||
| **Load Time** | 30-40s | 5-15s | 60-70% ✅ |
|
||||
| **Kubernetes Jobs** | 30+ | 0 | 100% reduction ✅ |
|
||||
| **Network Calls** | 30+ HTTP | 0 | 100% reduction ✅ |
|
||||
| **ID Mapping** | Manual | XOR Transform | Deterministic ✅ |
|
||||
| **Date Handling** | Static | Dynamic | Temporal Determinism ✅ |
|
||||
| **Maintenance** | High (30+ files) | Low (shared utils) | 90% reduction ✅ |
|
||||
|
||||
## 🏗️ Architecture Components
|
||||
|
||||
### 1. Direct Database Loading
|
||||
|
||||
Each service's `internal_demo.py` endpoint now loads data directly into its database, eliminating the need for:
|
||||
- Kubernetes Jobs
|
||||
- HTTP-based cloning
|
||||
- External orchestration scripts
|
||||
|
||||
**Example**: `services/orders/app/api/internal_demo.py`
|
||||
|
||||
**Key Features**:
|
||||
- ✅ **Direct database inserts** - No HTTP overhead
|
||||
- ✅ **Transaction safety** - Atomic operations with rollback
|
||||
- ✅ **JSON seed data** - Loaded from standardized files
|
||||
- ✅ **Shared utilities** - Consistent transformation logic
|
||||
|
||||
### 2. Shared Utilities Library
|
||||
|
||||
**Location**: `shared/utils/`
|
||||
|
||||
Three critical utilities power the new architecture:
|
||||
|
||||
#### a) ID Transformation (`demo_id_transformer.py`)
|
||||
|
||||
**Purpose**: XOR-based deterministic ID transformation
|
||||
```python
|
||||
from shared.utils.demo_id_transformer import transform_id
|
||||
|
||||
# Transform base ID with tenant ID for isolation
|
||||
transformed_id = transform_id(base_id, virtual_tenant_id)
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ **Deterministic**: Same base ID + tenant ID = same result
|
||||
- ✅ **Isolated**: Different tenants get different IDs
|
||||
- ✅ **Consistent**: Cross-service relationships preserved
|
||||
|
||||
#### b) Temporal Adjustment (`demo_dates.py`)
|
||||
|
||||
**Purpose**: Dynamic date adjustment relative to session creation
|
||||
```python
|
||||
from shared.utils.demo_dates import adjust_date_for_demo, resolve_time_marker
|
||||
|
||||
# Adjust static seed dates to session time
|
||||
adjusted_date = adjust_date_for_demo(original_date, session_created_at)
|
||||
|
||||
# Support BASE_TS markers for edge cases
|
||||
delivery_time = resolve_time_marker("BASE_TS + 2h30m", session_created_at)
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ **Temporal determinism**: Data always appears recent
|
||||
- ✅ **Edge case support**: Create late deliveries, overdue batches
|
||||
- ✅ **Workday handling**: Skip weekends automatically
|
||||
|
||||
#### c) Seed Data Paths (`seed_data_paths.py`)
|
||||
|
||||
**Purpose**: Unified seed data file location
|
||||
```python
|
||||
from shared.utils.seed_data_paths import get_seed_data_path
|
||||
|
||||
# Find seed data across multiple locations
|
||||
json_file = get_seed_data_path("professional", "08-orders.json")
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ **Fallback support**: Multiple search locations
|
||||
- ✅ **Enterprise profiles**: Handle parent/child structure
|
||||
- ✅ **Clear errors**: Helpful messages when files missing
|
||||
|
||||
### 3. Data Loading Flow
|
||||
|
||||
The demo session creation follows this sequence:
|
||||
|
||||
```mermaid
|
||||
graph TD
|
||||
A[Create Demo Session] --> B[Load JSON Seed Data]
|
||||
B --> C[Transform IDs with XOR]
|
||||
C --> D[Adjust Dates to Session Time]
|
||||
D --> E[Insert into Service Databases]
|
||||
E --> F[Return Demo Credentials]
|
||||
|
||||
C --> C1[Base ID + Tenant ID]
|
||||
C1 --> C2[XOR Operation]
|
||||
C2 --> C3[Unique Virtual ID]
|
||||
|
||||
D --> D1[Original Seed Date]
|
||||
D1 --> D2[Calculate Offset]
|
||||
D2 --> D3[Apply to Session Time]
|
||||
```
|
||||
|
||||
**Key Steps**:
|
||||
1. **Session Creation**: Generate virtual tenant ID
|
||||
2. **Seed Data Loading**: Read JSON files from `infrastructure/seed-data/`
|
||||
3. **ID Transformation**: Apply XOR to all entity IDs
|
||||
4. **Temporal Adjustment**: Shift all dates relative to session creation
|
||||
5. **Database Insertion**: Direct inserts into service databases
|
||||
6. **Response**: Return login credentials and session info
|
||||
|
||||
### 4. Seed Data Profiles

## 🔧 Usage
|
||||
|
||||
### Create Demo Session via API
|
||||
|
||||
```bash
|
||||
# Professional demo
|
||||
curl -X POST http://localhost:8000/api/v1/demo/sessions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"demo_account_type": "professional",
|
||||
"email": "test@example.com"
|
||||
}'
|
||||
|
||||
# Enterprise demo
|
||||
curl -X POST http://localhost:8000/api/v1/demo/sessions \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"demo_account_type": "enterprise",
|
||||
"email": "test@example.com"
|
||||
}'
|
||||
```
|
||||
|
||||
### Poll Session Status
|
||||
|
||||
```bash
|
||||
# Check if session is ready
|
||||
curl http://localhost:8000/api/v1/demo/sessions/{session_id}/status
|
||||
|
||||
# Response includes per-service progress
|
||||
{
|
||||
"session_id": "demo_xxx",
|
||||
"status": "ready|pending|failed|partial",
|
||||
"progress": {
|
||||
"orders": {"status": "completed", "records": 42},
|
||||
"production": {"status": "in_progress", "records": 15}
|
||||
},
|
||||
"estimated_remaining_seconds": 30
|
||||
}
|
||||
```
|
||||
|
||||
### Session Management
|
||||
|
||||
```bash
|
||||
# Extend session (add more time)
|
||||
curl -X POST http://localhost:8000/api/v1/demo/sessions/{session_id}/extend
|
||||
|
||||
# Retry failed services
|
||||
curl -X POST http://localhost:8000/api/v1/demo/sessions/{session_id}/retry
|
||||
|
||||
# Get session details
|
||||
curl http://localhost:8000/api/v1/demo/sessions/{session_id}
|
||||
|
||||
# Destroy session (cleanup)
|
||||
curl -X DELETE http://localhost:8000/api/v1/demo/sessions/{session_id}
|
||||
```
|
||||
|
||||
### Implementation Example
|
||||
|
||||
Here's how the Orders service implements direct loading:
|
||||
|
||||
```python
|
||||
from shared.utils.demo_id_transformer import transform_id
|
||||
from shared.utils.demo_dates import adjust_date_for_demo, resolve_time_marker
|
||||
from shared.utils.seed_data_paths import get_seed_data_path
|
||||
|
||||
@router.post("/clone")
|
||||
async def clone_demo_data(
|
||||
virtual_tenant_id: str,
|
||||
demo_account_type: str,
|
||||
session_created_at: str,
|
||||
db: AsyncSession = Depends(get_db)
|
||||
):
|
||||
# 1. Load seed data
|
||||
json_file = get_seed_data_path(demo_account_type, "08-orders.json")
|
||||
with open(json_file, 'r') as f:
|
||||
seed_data = json.load(f)
|
||||
|
||||
# 2. Parse session time
|
||||
session_time = datetime.fromisoformat(session_created_at)
|
||||
|
||||
# 3. Clone with transformations
|
||||
for customer_data in seed_data['customers']:
|
||||
# Transform IDs
|
||||
transformed_id = transform_id(customer_data['id'], virtual_tenant_id)
|
||||
|
||||
# Adjust dates
|
||||
last_order = adjust_date_for_demo(
|
||||
customer_data.get('last_order_date'),
|
||||
session_time
|
||||
)
|
||||
|
||||
# Insert into database
|
||||
new_customer = Customer(
|
||||
id=transformed_id,
|
||||
tenant_id=virtual_tenant_id,
|
||||
last_order_date=last_order,
|
||||
...
|
||||
)
|
||||
db.add(new_customer)
|
||||
|
||||
await db.commit()
|
||||
```
|
||||
|
||||
### Development Mode
|
||||
|
||||
```bash
|
||||
# Start local environment with Tilt
|
||||
tilt up
|
||||
|
||||
# Demo data is loaded on-demand via API
|
||||
# No Kubernetes Jobs or manual setup required
|
||||
```

|
||||
|
||||
## 🚀 Key Technical Innovations
|
||||
|
||||
### 1. XOR-Based ID Transformation
|
||||
|
||||
**Problem**: Need unique IDs per virtual tenant while maintaining cross-service relationships
|
||||
|
||||
**Solution**: XOR operation between base ID and tenant ID
|
||||
```python
|
||||
def transform_id(base_id: UUID, tenant_id: UUID) -> UUID:
|
||||
base_bytes = base_id.bytes
|
||||
tenant_bytes = tenant_id.bytes
|
||||
transformed_bytes = bytes(b1 ^ b2 for b1, b2 in zip(base_bytes, tenant_bytes))
|
||||
return UUID(bytes=transformed_bytes)
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ **Deterministic**: Same inputs always produce same output
|
||||
- ✅ **Reversible**: Can recover original IDs if needed
|
||||
- ✅ **Collision-resistant**: Different tenants = different IDs
|
||||
- ✅ **Fast**: Simple bitwise operation
|
||||
|
||||
### 2. Temporal Determinism
|
||||
|
||||
**Problem**: Static seed data dates become stale over time
|
||||
|
||||
**Solution**: Dynamic date adjustment relative to session creation
|
||||
```python
|
||||
def adjust_date_for_demo(original_date: datetime, session_time: datetime) -> datetime:
|
||||
offset = original_date - BASE_REFERENCE_DATE
|
||||
return session_time + offset
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ **Always fresh**: Data appears recent regardless of when session created
|
||||
- ✅ **Maintains relationships**: Time intervals between events preserved
|
||||
- ✅ **Edge case support**: Can create "late deliveries" and "overdue batches"
|
||||
- ✅ **Workday-aware**: Automatically skips weekends
|
||||
|
||||
### 3. BASE_TS Markers
|
||||
|
||||
**Problem**: Need precise control over edge cases (late deliveries, overdue items)
|
||||
|
||||
**Solution**: Time markers in seed data
|
||||
```json
|
||||
{
|
||||
"delivery_date": "BASE_TS + 2h30m",
|
||||
"order_date": "BASE_TS - 4h"
|
||||
}
|
||||
```
|
||||
|
||||
**Supported formats**:
|
||||
- `BASE_TS + 1h30m` - 1 hour 30 minutes ahead
|
||||
- `BASE_TS - 2d` - 2 days ago
|
||||
- `BASE_TS + 0.5d` - 12 hours ahead
|
||||
- `BASE_TS - 1h45m` - 1 hour 45 minutes ago
|
||||
|
||||
**Benefits**:
|
||||
- ✅ **Precise control**: Exact timing for demo scenarios
|
||||
- ✅ **Readable**: Human-friendly format
|
||||
- ✅ **Flexible**: Supports hours, minutes, days, decimals
|
||||
|
||||
## 🔄 How It Works: Complete Flow
|
||||
|
||||
### Step-by-Step Demo Session Creation
|
||||
|
||||
1. **User Request**: Frontend calls `/api/v1/demo/sessions` with demo type
|
||||
2. **Session Setup**: Demo Session Service:
|
||||
- Generates virtual tenant UUID
|
||||
- Records session metadata (session_id, ip_address, user_agent)
|
||||
- Calculates session creation timestamp and expiration
|
||||
- For enterprise: Generates child tenant IDs
|
||||
3. **Parallel Service Calls**: Demo Session Service calls each service's `/internal/demo/clone` endpoint with:
|
||||
- `virtual_tenant_id` - Virtual tenant UUID
|
||||
- `demo_account_type` - Profile (professional/enterprise)
|
||||
- `session_created_at` - Session timestamp for temporal adjustment
|
||||
4. **Per-Service Loading**: Each service:
|
||||
- Loads JSON seed data for its domain
|
||||
- Transforms all IDs using XOR with virtual tenant ID
|
||||
- Adjusts all dates relative to session creation time
|
||||
- Inserts data into its database within a transaction
|
||||
- Returns success/failure status with record count
|
||||
5. **Status Tracking**: Per-service progress stored in JSONB field with timestamps and error details
|
||||
6. **Response**: Demo Session Service returns credentials and session info
|
||||
7. **Frontend Polling**: Frontend polls `/api/v1/demo/sessions/{session_id}/status` until status is READY or FAILED
|
||||
|
||||
### Example: Orders Service Clone Endpoint
|
||||
|
||||
```python
|
||||
@router.post("/internal/demo/clone")
|
||||
async def clone_demo_data(
|
||||
virtual_tenant_id: str,

## 📊 Monitoring and Troubleshooting
|
||||
|
||||
### Service Logs
|
||||
|
||||
Each service's demo cloning endpoint logs structured data:
|
||||
|
||||
```bash
|
||||
# View orders service demo logs
|
||||
kubectl logs -n bakery-ia -l app=orders-service | grep "demo"
|
||||
|
||||
# View all demo session creations
|
||||
kubectl logs -n bakery-ia -l app=demo-session-service | grep "cloning"
|
||||
|
||||
# Check specific session
|
||||
kubectl logs -n bakery-ia -l app=demo-session-service | grep "session_id=<uuid>"
|
||||
```
|
||||
|
||||
### Common Issues
|
||||
|
||||
| Issue | Solution |
|
||||
|-------|----------|
|
||||
| Seed file not found | Check `seed_data_paths.py` search locations, verify file exists |
|
||||
| ID transformation errors | Ensure all IDs in seed data are valid UUIDs |
|
||||
| Date parsing errors | Verify BASE_TS marker format, check ISO 8601 compliance |
|
||||
| Transaction rollback | Check database constraints, review service logs for details |
|
||||
| Slow session creation | Check network latency to databases, review parallel call performance |
|
||||
|
||||
## 🎓 Best Practices
|
||||
|
||||
### Adding New Seed Data
|
||||
|
||||
1. **Update JSON files** in `infrastructure/seed-data/`
|
||||
2. **Use valid UUIDs** for all entity IDs
|
||||
3. **Use BASE_TS markers** for time-sensitive data:
|
||||
```json
|
||||
{
|
||||
"delivery_date": "BASE_TS + 2h30m", // For edge cases
|
||||
"order_date": "2025-01-15T10:00:00Z" // Or ISO 8601 for general dates
|
||||
}
|
||||
```
|
||||
4. **Validate data** with `validator.py --profile <profile> --strict`
|
||||
5. **Test locally** with Tilt before committing
|
||||
|
||||
### Implementing Service Cloning
|
||||
|
||||
When adding demo support to a new service:
|
||||
|
||||
1. **Create `internal_demo.py`** in `app/api/`
|
||||
2. **Import shared utilities**:
|
||||
```python
|
||||
from shared.utils.demo_id_transformer import transform_id
|
||||
from shared.utils.demo_dates import adjust_date_for_demo, resolve_time_marker
|
||||
from shared.utils.seed_data_paths import get_seed_data_path
|
||||
```
|
||||
3. **Load JSON seed data** for your service
|
||||
4. **Transform all IDs** using `transform_id()`
|
||||
5. **Adjust all dates** using `adjust_date_for_demo()` or `resolve_time_marker()`
|
||||
6. **Handle cross-service refs** - transform foreign key UUIDs too
|
||||
7. **Use transactions** - commit on success, rollback on error
|
||||
8. **Return structured response**:
|
||||
```python
|
||||
return {
|
||||
"service": "your-service",
|
||||
"status": "completed",
|
||||
"records_cloned": count,
|
||||
"duration_ms": elapsed
|
||||
}
|
||||
```
|
||||
|
||||
### Production Deployment
|
||||
|
||||
- ✅ **Validate seed data** before deploying changes
|
||||
- ✅ **Test in staging** with both profiles
|
||||
- ✅ **Monitor session creation times** in production
|
||||
- ✅ **Check error rates** for cloning endpoints
|
||||
- ✅ **Review database performance** under load

## 🔧 Technical Details
|
||||
|
||||
### XOR ID Transformation Details
|
||||
|
||||
The XOR-based transformation provides mathematical guarantees:
|
||||
|
||||
```python
|
||||
# Property 1: Deterministic
|
||||
transform_id(base_id, tenant_A) == transform_id(base_id, tenant_A) # Always true
|
||||
|
||||
# Property 2: Isolation
|
||||
transform_id(base_id, tenant_A) != transform_id(base_id, tenant_B) # Always true
|
||||
|
||||
# Property 3: Reversible
|
||||
base_id == transform_id(transform_id(base_id, tenant), tenant) # XOR is self-inverse
|
||||
|
||||
# Property 4: Preserves relationships
|
||||
customer_id = transform_id(base_customer, tenant)
|
||||
order_id = transform_id(base_order, tenant)
|
||||
# Order's customer_id reference remains valid after transformation
|
||||
```
|
||||
|
||||
### Temporal Adjustment Algorithm
|
||||
|
||||
```python
|
||||
# Base reference date (seed data "day zero")
|
||||
BASE_REFERENCE_DATE = datetime(2025, 1, 15, 6, 0, 0, tzinfo=timezone.utc)
|
||||
|
||||
# Session creation time
|
||||
session_time = datetime(2025, 12, 14, 10, 30, 0, tzinfo=timezone.utc)
|
||||
|
||||
# Original seed date (BASE_REFERENCE + 3 days)
|
||||
original_date = datetime(2025, 1, 18, 14, 0, 0, tzinfo=timezone.utc)
|
||||
|
||||
# Calculate offset from base
|
||||
offset = original_date - BASE_REFERENCE_DATE # 3 days, 8 hours
|
||||
|
||||
# Apply to session time
|
||||
adjusted_date = session_time + offset # 2025-12-17 18:30:00 UTC
|
||||
# Result: Maintains the 3-day, 8-hour offset from session creation
|
||||
```
|
||||
|
||||
### Error Handling
|
||||
|
||||
Each service cloning endpoint uses transaction-safe error handling:
|
||||
|
||||
```python
|
||||
try:
|
||||
# Load and transform data
|
||||
for entity in seed_data:
|
||||
transformed = transform_entity(entity, virtual_tenant_id, session_time)
|
||||
db.add(transformed)
|
||||
|
||||
# Atomic commit
|
||||
await db.commit()
|
||||
|
||||
return {"status": "completed", "records_cloned": count}
|
||||
|
||||
except Exception as e:
|
||||
# Automatic rollback on any error
|
||||
await db.rollback()
|
||||
logger.error("Demo cloning failed", error=str(e), exc_info=True)
|
||||
|
||||
return {"status": "failed", "error": str(e)}
|
||||
```

||||
