Previously, we built a theoretical foundation of Distributed Transaction using the Two-Phase Commit protocol. In this video, we implement the Distributed Transaction locally and mimic the food delivery system locally. While implementing we understand how to make the individual operations atomic and the entire distributed transaction atomic. We address resource contention while guaranteeing a consistent user experience.

# Arpit's System Design Masterclass

I teach an 8-week cohort-based course on System Design - a masterclass that helps you become great at designing scalable, fault-tolerant, and highly available systems.

The program will have a blend of Live Classes happening on weekends, 1:1 Mentorship sessions happening on weekdays. The program is designed to be intense and crisp to accelerate overall learning.

You can find more details about the program at https://arpitbhayani.me/masterclass.
