This guide outlines best practices for optimizing performance when using the Thena Platform, ensuring your applications run efficiently and scale effectively.

​
API Optimization

​
Request Management

// Example: Implementing request batching
const batchRequests = async (requests: Request[]): Promise<Response[]> => {
  const batchSize = 10;
  const results = [];
  
  for (let i = 0; i < requests.length; i += batchSize) {
    const batch = requests.slice(i, i + batchSize);
    const batchResults = await Promise.all(batch.map(processRequest));
    results.push(...batchResults);
  }
  
  return results;
};
  • Implement request batching
  • Use pagination for large datasets
  • Optimize query parameters
  • Cache frequently accessed data
  • Implement rate limiting

​
Response Optimization

// Example: Implementing field selection
const getUser = async (id: string, fields: string[]): Promise<User> => {
  const projection = fields.reduce((acc, field) => ({...acc, [field]: 1}), {});
  return await db.users.findOne({ id }, { projection });
};
  • Implement field selection
  • Compress responses
  • Use appropriate data formats
  • Optimize payload size
  • Cache responses

​
Caching Strategies

​
Client-Side Caching

// Example: Implementing a cache wrapper
class Cache {
  private store: Map<string, {data: any, expiry: number}>;
  
  set(key: string, data: any, ttl: number): void {
    this.store.set(key, {
      data,
      expiry: Date.now() + ttl
    });
  }
  
  get(key: string): any {
    const item = this.store.get(key);
    if (!item || item.expiry < Date.now()) {
      return null;
    }
    return item.data;
  }
}
  • Implement browser caching
  • Use service workers
  • Local storage optimization
  • Memory cache management
  • Cache invalidation strategies

​
Server-Side Caching

  • Use Redis for distributed caching
  • Implement query caching
  • Cache warm-up strategies
  • Cache eviction policies
  • Monitor cache hit rates

​
Database Optimization

​
Query Optimization

-- Example: Optimizing database queries
CREATE INDEX idx_user_email ON users(email);
CREATE INDEX idx_ticket_status ON tickets(status, created_at);
  • Proper indexing
  • Query optimization
  • Connection pooling
  • Regular maintenance
  • Performance monitoring

​
Data Management

  • Implement data archiving
  • Regular cleanup jobs
  • Optimize table structure
  • Manage data growth
  • Monitor database metrics

​
Resource Management

​
Memory Management

// Example: Implementing memory monitoring
const monitorMemoryUsage = (): void => {
  const used = process.memoryUsage();
  console.log({
    heapTotal: `${Math.round(used.heapTotal / 1024 / 1024)} MB`,
    heapUsed: `${Math.round(used.heapUsed / 1024 / 1024)} MB`,
    external: `${Math.round(used.external / 1024 / 1024)} MB`
  });
};
  • Monitor memory usage
  • Implement garbage collection
  • Memory leak prevention
  • Resource pooling
  • Load balancing

​
CPU Optimization

  • Optimize compute-intensive tasks
  • Use worker threads
  • Implement task queuing
  • Monitor CPU usage
  • Resource allocation

​
Network Optimization

​
Content Delivery

// Example: CDN configuration
const cdnConfig = {
  enabled: true,
  baseUrl: 'https://cdn.thena.ai',
  cacheControl: 'public, max-age=31536000',
  regions: ['us-east-1', 'eu-west-1', 'ap-southeast-1']
};
  • Use CDN for static content
  • Image optimization
  • Asset compression
  • Lazy loading
  • Preloading critical resources

​
Connection Management

  • Keep-alive connections
  • Connection pooling
  • Request pipelining
  • DNS optimization
  • Load balancing

​
Monitoring & Metrics

​
Performance Monitoring

// Example: Performance metric tracking
const trackMetric = async (metric: string, value: number): Promise<void> => {
  await metrics.push({
    name: metric,
    value,
    timestamp: Date.now(),
    tags: {
      environment: process.env.NODE_ENV,
      region: process.env.REGION
    }
  });
};
  • Monitor response times
  • Track error rates
  • Measure throughput
  • Resource utilization
  • User experience metrics

​
Alerting

  • Set performance thresholds
  • Configure alerts
  • Monitor trends
  • Incident response
  • Performance reporting
