DB Replication Architectures Explained | Master-Slave, Multi-Master & Masterless | System Design #10

🚀 Welcome to Episode 10 of the System Design Series! In the previous videos, we explored Synchronous and Asynchronous Database Replication. But what happens when the traditional Master-Slave architecture becomes a bottleneck? In this video, we'll explore different Database Replication Architectures and understand how systems evolve from Master-Slave to Multi-Master and finally to Masterless architectures. 📚 In this video, you'll learn: ✅ Master-Slave / Primary-Replica Architecture ✅ Drawbacks of Master-Slave Architecture • Single Point of Failure • Write Bottleneck • Limited Write Scalability ✅ Multi-Master Architecture ✅ How Multi-Master Replication Works ✅ Drawbacks of Multi-Master • Conflict Resolution • Data Consistency Challenges ✅ Masterless Architecture ✅ How Masterless Databases Work ✅ Understanding Quorums ✅ Read Quorum (R) ✅ Write Quorum (W) ✅ Number of Replicas (N) ✅ Quorum Formula ✅ How Reads and Writes work in a Masterless Architecture ✅ Availability and Fault Tolerance 💡 We'll also walk through the Masterless architecture step-by-step using an interactive UI example to make the replication and quorum concepts easier to understand. 📺 Complete High-Level Design (HLD) Playlist: 🔗    • System Design | Complete High-Level Design...   📌 Previous Videos: Episode 1 – What is System Design?
