Technical Constraints

System Requirements

  • Docker environment for containerization
  • Sufficient disk space for file processing
  • Memory for concurrent processing jobs

API Limitations

  • File size limits based on server configuration
  • Processing time varies with document complexity
  • Concurrent job limits based on server resources

Security Considerations

  • CORS configured for frontend-backend communication
  • File upload restrictions and sanitization
  • Environment variable management for API keys

Performance Considerations

  • Asynchronous processing for large files
  • Progress tracking for long-running operations
  • Memory management for concurrent jobs
