## 🏛️ Architectural Patterns
### **1. Microservices Architecture**
The platform is decomposed into independently deployable services:
```
┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐
│ Frontend │ │ API Gateway │ │ Worker │
│ - Next.js │ │ - Authentication│ │ - Image Proc. │
│ - UI/UX │ │ - Rate Limiting│ │ - AI Analysis │
│ - Real-time │ │ - Validation │ │ - Virus Scan │
└─────────────────┘ └─────────────────┘ └─────────────────┘
│
┌─────────────────┐
│ Monitoring │
│ - Metrics │
│ - Health │
│ - Alerts │
└─────────────────┘
```
**Benefits:**
- Independent scaling and deployment
- Technology diversity (different services can use different tech stacks)
- Fault isolation (failure in one service doesn't affect others)
- Team autonomy (different teams can own different services)
### **2. Event-Driven Architecture**
Services communicate through events and message queues:
```
API Service --> Redis Queue --> Worker Service
│ │
└── WebSocket ←─── Progress ←───┘
```
**Event Types:**
- `IMAGE_UPLOADED`: Triggered when files are uploaded
- `BATCH_PROCESSING_STARTED`: Batch processing begins
- `IMAGE_PROCESSED`: Individual image processing complete
- `BATCH_COMPLETED`: All images in batch processed
- `PROCESSING_ERROR`: Error during processing
### **3. Repository Pattern**
Data access is abstracted through repository interfaces:
```typescript
interface UserRepository {
findById(id: string): Promise<User>;
updateQuota(userId: string, used: number): Promise<void>;
upgradeUserPlan(userId: string, plan: Plan): Promise<void>;
}
class PrismaUserRepository implements UserRepository {
// Implementation using Prisma ORM
}
```
**Benefits:**
- Testability (easy to mock repositories)
- Database independence (can switch ORMs/databases)
- Clear separation of business logic and data access
## 💾 Data Architecture
### **Database Schema (PostgreSQL)**
```sql
-- Users table with OAuth integration
CREATE TABLE users (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
google_id VARCHAR(255) UNIQUE NOT NULL,
email_hash VARCHAR(64) NOT NULL, -- SHA-256 hashed
display_name VARCHAR(255),
plan user_plan DEFAULT 'BASIC',
quota_limit INTEGER NOT NULL,
quota_used INTEGER DEFAULT 0,
created_at TIMESTAMP DEFAULT NOW(),
updated_at TIMESTAMP DEFAULT NOW()
);
-- Batches for image processing sessions
CREATE TABLE batches (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
user_id UUID REFERENCES users(id) ON DELETE CASCADE,
status batch_status DEFAULT 'PENDING',
total_images INTEGER DEFAULT 0,
processed_images INTEGER DEFAULT 0,
keywords TEXT[], -- User-provided keywords
created_at TIMESTAMP DEFAULT NOW(),
completed_at TIMESTAMP
);
-- Individual images in processing batches
CREATE TABLE images (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
batch_id UUID REFERENCES batches(id) ON DELETE CASCADE,
original_name VARCHAR(255) NOT NULL,
proposed_name VARCHAR(255),
file_path VARCHAR(500) NOT NULL,
file_size BIGINT NOT NULL,
mime_type VARCHAR(100) NOT NULL,
checksum VARCHAR(64) NOT NULL, -- SHA-256
vision_tags JSONB, -- AI-generated tags
status image_status DEFAULT 'PENDING',
created_at TIMESTAMP DEFAULT NOW(),
processed_at TIMESTAMP
);
-- Payment transactions and subscriptions
CREATE TABLE payments (
id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
user_id UUID REFERENCES users(id) ON DELETE CASCADE,
stripe_session_id VARCHAR(255) UNIQUE,
stripe_subscription_id VARCHAR(255),
plan user_plan NOT NULL,
amount INTEGER NOT NULL, -- cents
currency VARCHAR(3) DEFAULT 'USD',
status payment_status DEFAULT 'PENDING',
created_at TIMESTAMP DEFAULT NOW(),
completed_at TIMESTAMP
);
```
### **Indexing Strategy**
```sql
-- Performance optimization indexes
CREATE INDEX idx_users_google_id ON users(google_id);
CREATE INDEX idx_users_email_hash ON users(email_hash);
CREATE INDEX idx_batches_user_id ON batches(user_id);
CREATE INDEX idx_batches_status ON batches(status);
CREATE INDEX idx_images_batch_id ON images(batch_id);
CREATE INDEX idx_images_checksum ON images(checksum);
CREATE INDEX idx_payments_user_id ON payments(user_id);
CREATE INDEX idx_payments_stripe_session ON payments(stripe_session_id);
-- Composite indexes for common queries
CREATE INDEX idx_images_batch_status ON images(batch_id, status);
CREATE INDEX idx_batches_user_created ON batches(user_id, created_at DESC);
```

## Performance
### Throughput
- **Images/minute**: 50-100 (depending on AI provider limits)
- **Concurrent jobs**: Configurable (default: 5)
- **File size limit**: 50MB (configurable)
### Resource Usage
- **Memory**: ~200MB base + ~50MB per concurrent job
- **CPU**: ~100% per active image processing job
- **Storage**: Temporary files cleaned automatically
## Monitoring
### Key Metrics
- `seo_worker_jobs_total` - Total jobs processed
- `seo_worker_job_duration_seconds` - Processing time distribution
- `seo_worker_vision_api_calls_total` - AI API usage
- `seo_worker_processing_errors_total` - Error rates
### Alerts
- High error rates (>5%)
- API rate limit approaching
- Queue backlog growing
- Storage space low
- Memory usage high
## Troubleshooting
### Common Issues
1. **AI Vision API Failures**
```bash
# Check API keys and quotas
curl -H "Authorization: Bearer $OPENAI_API_KEY" https://api.openai.com/v1/models
```
2. **Storage Connection Issues**
```bash
# Test MinIO connection
mc alias set local http://localhost:9000 access_key secret_key
mc ls local
```
3. **Queue Processing Stopped**
```bash
# Check Redis connection
redis-cli ping
# Check queue status
curl http://localhost:3002/health/detailed
```
4. **High Memory Usage**
```bash
# Check temp file cleanup
ls -la /tmp/seo-worker/
# Force cleanup
curl -X POST http://localhost:3002/admin/cleanup
```
### Debugging
Enable debug logging:
```env
LOG_LEVEL=debug
NODE_ENV=development
```
Monitor processing in real-time:
```bash
# Follow logs
docker logs -f seo-worker
# Monitor metrics
curl http://localhost:9090/metrics | grep seo_worker
```
