PERF-002: File Upload and Storage Optimization

[raviyelisetty]

Description:

Optimize file upload, storage, and delivery for better performance and user experience.

Optimization Components:

Upload Performance

• Chunked file upload for large files
• Parallel upload processing
• Client-side compression before upload
• Upload progress tracking and resumption

Storage Optimization

• Automatic image compression and optimization
• Multiple format generation (WebP, AVIF)
• Intelligent thumbnail generation
• Duplicate file detection and deduplication

Content Delivery

• CDN integration for global distribution
• Adaptive bitrate for video content
• Lazy loading for images
• Progressive image enhancement

Implementation Features

typescript
interface FileOptimization {
  upload: {
    chunkSize: number; // 5MB chunks
    maxConcurrent: number; // 3 parallel uploads
    compression: {
      images: { quality: 85, format: 'webp' };
      videos: { codec: 'h264', bitrate: '1000k' };
    };
  };
  storage: {
    deduplication: boolean;
    thumbnails: Array<{ width: number; height: number }>;
    formats: string[]; // ['webp', 'jpeg', 'png']
  };
  delivery: {
    cdn: {
      provider: 'cloudflare';
      regions: string[];
      cacheControl: string;
    };
    adaptive: boolean;
  };
}

Storage Structure:

• Original files preserved
• Multiple optimized variants
• Metadata tracking for all versions
• Automatic cleanup of unused files

Acceptance Criteria:

• 50% faster file upload speeds
• 70% reduction in storage usage
• CDN integration operational
• Automatic image optimization
• Progressive loading implementation
• File storage analytics
• Backup and recovery procedures

Estimated Effort: 16-20 hours
