Day 7: Quiz Session Management - Building Robust Session Tracking for Scale
60-Days Hands-On AI-Engineering Series
The Challenge: Keeping Track of Millions of Quiz Attempts
Imagine you're Netflix, but instead of tracking what episode someone watched last, you're tracking where students left off in their quizzes. When a student accidentally closes their browser mid-quiz, can your system remember their progress? When your server crashes during peak hours, do thousands of students lose their work? This is the core challenge of session management in distributed systems.
Today, we're building a quiz attempt tracking service that can handle real-world scale - the kind of system that powers platforms like Khan Academy or Coursera, where millions of students take quizzes simultaneously.
