How Distributed Databases Ensure Data Integrity: The Two-Phase Commit Protocol
Have you ever wondered how large-scale distributed systems, like Google Spanner, ensure data consistency across multiple servers? The answer lies in **Atomicity**—a principle that ensures a transaction is **all or nothing**.
In this video, we dive deep into:
✅ The concept of *Atomicity* and why it's critical for distributed databases.
✅ The *Two-Phase Commit Protocol (2PC)* and how it works.
✅ Step-by-step breakdown of the *Prepare Phase* and *Commit Phase* using a real-world scenario.
✅ A detailed walkthrough of the *sequence diagram* illustrating how the coordinator and partitions communicate.
✅ Why Atomicity is essential for preventing inconsistent data states in global systems like Google Spanner.
