## Enterprise Features

### Performance & Scalability

| Feature | Description | Benefit |
|---------|-------------|---------|
| **JSON Passthrough** | Zero-copy JSON processing | 99% faster responses |
| **APQ** | Persisted query caching | 90% bandwidth reduction |
| **DataLoader** | Automatic batching | Eliminates N+1 queries |
| **Connection Pooling** | PostgreSQL connection management | 10x more concurrent users |
| **Read Replicas** | CQRS with read/write separation | Unlimited read scalability |

### Security & Compliance

| Feature | Description | Compliance |
|---------|-------------|------------|
| **Field Authorization** | Decorator-based access control | SOC 2, GDPR |
| **Row-Level Security** | PostgreSQL RLS integration | HIPAA, PCI DSS |
| **Unified Audit Logging** | Cryptographic chain integrity with CDC | SOX, HIPAA, SOC 2 |
| **Data Masking** | PII field redaction | GDPR, CCPA |
| **Session Variables** | Tenant isolation | Multi-tenancy |

#### Unified Audit Table Architecture

FraiseQL uses a **single unified audit table** that combines:
- ✅ **CDC (Change Data Capture)** - old_data, new_data, changed_fields
- ✅ **Cryptographic chain integrity** - event_hash, signature, previous_hash
- ✅ **Business metadata** - operation types, business_actions
- ✅ **Multi-tenant isolation** - per-tenant cryptographic chains

**Why One Table?**
- **Simplicity**: One schema to understand, one table to query
- **Performance**: No duplicate writes, no bridge synchronization
- **Integrity**: Single source of truth, atomic operations
- **Philosophy**: "In PostgreSQL Everything" - all logic in PostgreSQL

**Querying Audit Trail:**
```sql
-- Get complete audit history for a user
SELECT timestamp, operation_type, entity_type, entity_id,
       old_data, new_data, changed_fields, metadata
FROM audit_events
WHERE tenant_id = $1 AND entity_type = 'user' AND entity_id = $2
ORDER BY timestamp DESC;

-- Verify cryptographic chain integrity
SELECT verify_audit_chain($tenant_id, $start_date, $end_date);
```

**Cryptographic Chain Verification:**
```sql
-- Check if audit trail has been tampered with
SELECT event_id, chain_valid, expected_hash, actual_hash
FROM verify_audit_chain('tenant-123'::UUID);
-- Returns TRUE for all events if chain is intact
```

### Observability & Monitoring

| Feature | Description | Use Case |
|---------|-------------|----------|
| **Prometheus Metrics** | RED metrics (Rate, Errors, Duration) | SLA monitoring |
| **OpenTelemetry** | Distributed tracing | Performance debugging |
| **Sentry Integration** | Error tracking with context | Proactive issue resolution |
| **Health Checks** | Liveness, readiness, startup probes | Kubernetes orchestration |
| **Grafana Dashboards** | Pre-built monitoring dashboards | Operational visibility |

kubectl port-forward svc/fraiseql 8000:80
curl http://localhost:8000/graphql
```

### Configuration for Production

```python
from fraiseql import FraiseQL
from fraiseql.monitoring import init_sentry, setup_metrics, HealthCheck
from fraiseql.monitoring import check_database, check_pool_stats

# Initialize error tracking
init_sentry(
    dsn=os.getenv("SENTRY_DSN"),
    environment="production",
    traces_sample_rate=0.1,
    profiles_sample_rate=0.1,
    release=f"fraiseql@{VERSION}"
)

# Configure metrics
setup_metrics(MetricsConfig(
    enabled=True,
    include_graphql=True,
    include_database=True
))

# Set up health checks
health = HealthCheck()
health.add_check("database", check_database)
health.add_check("pool", check_pool_stats)

@app.get("/health")
async def health_check():
    result = await health.run_checks()
    return result

# Create FraiseQL app
fraiseql = FraiseQL(
    db_url=os.getenv("DATABASE_URL"),
    cqrs_read_urls=[os.getenv("READ_REPLICA_1"), os.getenv("READ_REPLICA_2")],
    production=True,
    enable_introspection=False,
    enable_playground=False,
