const timeSeries = await synth.generateTimeSeries({
  count: 90,
  interval: '1d',
  metrics: ['impressions', 'clicks', 'conversions', 'spend', 'revenue', 'roas'],
  trend: 'up',
  seasonality: true,
  constraints: {
    roas: { min: 1.0, max: 10.0 }
  }
});
```

### Multi-Platform Batch Generation

```typescript
// Generate data for multiple platforms in parallel
const platforms = [
  { count: 50, constraints: { platform: 'Google Ads' } },
  { count: 50, constraints: { platform: 'Facebook Ads' } },
  { count: 50, constraints: { platform: 'TikTok Ads' } }

  },
  constraints: {
    objective: ['conversions', 'app_install', 'video_views'],
    videoCompletionRate: { min: 0.1, max: 0.8 }
  }
});
```

## Advanced Features

### Streaming Real-Time Data

```typescript
// Stream campaign metrics in real-time
const synth = createSynth({ streaming: true });

for await (const metric of synth.generateStream('structured', {
  count: 100,
  schema: {
    timestamp: { type: 'string' },
    roas: { type: 'number' },
    alert: { type: 'string' }
  }
})) {
  console.log('Real-time metric:', metric);

  // Trigger alerts based on ROAS
  if (metric.roas < 1.0) {
    console.log('⚠️ ROAS below target!');
  }
}
```

### Caching for Performance

```typescript
// Use caching for repeated queries
const synth = createSynth({
  cacheStrategy: 'memory',
  cacheTTL: 600 // 10 minutes
});

// First call generates data
const data1 = await synth.generateStructured({ count: 100, schema });

// Second call uses cache (much faster)
const data2 = await synth.generateStructured({ count: 100, schema });
```

### Custom Constraints

```typescript
// Apply realistic business constraints
const campaigns = await synth.generateStructured({
  count: 50,
  schema: campaignSchema,
  constraints: {
    // Budget constraints
    spend: { min: 1000, max: 50000 },

    // Performance constraints
    roas: { min: 2.0, max: 10.0 },
    cpa: { max: 50.0 },

    // Volume constraints
    impressions: { min: 10000 },
    clicks: { min: 100 },
    conversions: { min: 10 },

    // Platform-specific
    platform: ['Google Ads', 'Facebook Ads'],
    status: ['active', 'paused']
  }
});
```

## Integration Examples

### Data Warehouse Pipeline

```typescript
import { generateTimeSeriesCampaignData } from './campaign-data.js';

async function loadToWarehouse() {
  const campaigns = await generateTimeSeriesCampaignData();

  // Transform to warehouse schema
  const rows = campaigns.data.map(campaign => ({
    date: campaign.timestamp,
    platform: campaign.platform,
    metrics: {
      impressions: campaign.impressions,
      clicks: campaign.clicks,
      spend: campaign.spend,
      revenue: campaign.revenue,
      roas: campaign.roas
    }
  }));

  // Load to BigQuery, Snowflake, Redshift, etc.
  await warehouse.bulkInsert('campaigns', rows);
}
```

### BI Tool Testing

```typescript
import { generateChannelComparison } from './analytics-pipeline.js';

async function generateBIReport() {
  const comparison = await generateChannelComparison();

  // Export for Tableau, Looker, Power BI
  const csv = convertToCSV(comparison.data);
  await fs.writeFile('channel_performance.csv', csv);
}
```

### ML Model Training

```typescript
import { generateLTVAnalysis } from './analytics-pipeline.js';

async function trainPredictiveModel() {
  // Generate training data
  const ltvData = await generateLTVAnalysis();

  // Features for ML model
  const features = ltvData.data.map(cohort => ({
    acquisitionChannel: cohort.acquisitionChannel,
    firstPurchase: cohort.metrics.avgFirstPurchase,
    frequency: cohort.metrics.purchaseFrequency,
    retention: cohort.metrics.retentionRate,
    // Target variable
    ltv: cohort.ltvCalculations.predictiveLTV
  }));

  // Train with TensorFlow, scikit-learn, etc.
  await model.train(features);
}
```

## Best Practices

### 1. Use Realistic Constraints

```typescript
// ✅ Good: Realistic business constraints
const campaigns = await synth.generateStructured({
  constraints: {
    roas: { min: 0.5, max: 15.0 },  // Typical range
    ctr: { min: 0.01, max: 0.15 },   // 1-15%
    cvr: { min: 0.01, max: 0.20 }    // 1-20%
  }
});

// ❌ Bad: Unrealistic values
const bad = await synth.generateStructured({
  constraints: {
    roas: { min: 50.0 },  // Too high
    ctr: { min: 0.5 }     // 50% CTR unrealistic
  }
});
```

### 2. Match Platform Characteristics

```typescript
// Different platforms have different metrics
const googleAds = {
  qualityScore: { min: 1, max: 10 },
  avgPosition: { min: 1.0, max: 5.0 }
};

const facebookAds = {
  relevanceScore: { min: 1, max: 10 },
  frequency: { min: 1.0, max: 5.0 }
};

const tiktokAds = {
  videoCompletionRate: { min: 0.1, max: 0.8 },
  engagement: { min: 0.02, max: 0.15 }
};
```

### 3. Consider Seasonality

```typescript
// Include seasonal patterns for realistic data
const seasonal = await synth.generateTimeSeries({
  count: 365,
  interval: '1d',
  seasonality: true,  // Includes weekly/monthly patterns
  trend: 'up',        // Long-term growth
  noise: 0.15         // 15% random variation
});
```

### 4. Use Batch Processing

```typescript
// Generate large datasets efficiently
const batches = Array.from({ length: 10 }, (_, i) => ({
  count: 1000,
  schema: campaignSchema
}));

const results = await synth.generateBatch('structured', batches, 5);
// Processes 10,000 records in parallel
```

## Performance Tips

1. **Enable Caching**: Reuse generated data for similar queries
2. **Batch Operations**: Generate multiple datasets in parallel
3. **Streaming**: Use for real-time or large datasets
4. **Constraints**: Be specific to reduce generation time
5. **Schema Design**: Simpler schemas generate faster

## Testing Scenarios

### Unit Testing

```typescript
import { generateGoogleAdsCampaign } from './campaign-data.js';

describe('Campaign Data Generator', () => {
  it('should generate valid ROAS values', async () => {
    const result = await generateGoogleAdsCampaign();

    result.data.forEach(campaign => {
      expect(campaign.roas).toBeGreaterThanOrEqual(0.5);
      expect(campaign.roas).toBeLessThanOrEqual(8.0);
    });
  });
});
```

### Integration Testing

```typescript
import { runAnalyticsExamples } from './analytics-pipeline.js';

async function testAnalyticsPipeline() {
  // Generate test data
  await runAnalyticsExamples();

  // Verify pipeline processes data correctly
  const processed = await pipeline.run();

  expect(processed.success).toBe(true);
}
```

## Troubleshooting

### API Key Issues

```typescript
// Ensure API key is set
if (!process.env.GEMINI_API_KEY) {
  throw new Error('GEMINI_API_KEY not found');
}

const synth = createSynth({
  provider: 'gemini',
  apiKey: process.env.GEMINI_API_KEY
});
```

### Rate Limiting

```typescript
// Use retry logic for rate limits
const synth = createSynth({
  maxRetries: 5,
  timeout: 60000  // 60 seconds
});
```

### Memory Management

```typescript
// Use streaming for large datasets
const synth = createSynth({ streaming: true });

for await (const chunk of synth.generateStream('structured', {
  count: 100000,
  schema: simpleSchema
})) {
  await processChunk(chunk);
  // Process in batches to avoid memory issues
}
```
