Скачать или смотреть System Design Interview Prep: Demystifying Three-Phase Commit (3PC)

Ever heard of Two-Phase Commit (2PC) but wondered about its "blocking problem"? 🤔 Dive into the Three-Phase Commit (3PC) protocol – a more complex distributed transaction algorithm designed to solve 2PC's notorious blocking flaw!

In this video, we'll cover:

What 3PC is: An extension of 2PC aiming for non-blocking atomic commitment.

The Problem it Solves: How it attempts to overcome 2PC's resource-holding issues during coordinator failure.

How 3PC Works: A detailed breakdown of its three phases – Vote Request, Pre-Commit, and Commit.

Advantages & Disadvantages: Why 3PC is theoretically non-blocking in some scenarios, but its practical limitations and reasons for rare adoption.

System Design Interview Insights: How to discuss 3PC to show a comprehensive understanding of distributed transaction complexities.
