MongoDB Multi-Document ACID Transactions Explained

Описание: In this video, we dive deep into MongoDB Multi-Document ACID Transactions and explain how a traditionally NoSQL database delivers strong consistency, atomicity, and isolation across multiple documents.

MongoDB originally relied on single-document atomicity, but real-world use cases like financial systems, distributed workflows, and mission-critical applications demanded stronger guarantees. This video breaks down the multi-year engineering roadmap that made ACID transactions possible—without sacrificing scalability.

🔍 What’s Covered:

Why ACID transactions are hard in distributed NoSQL systems

The role of the WiredTiger storage engine

Logical sessions, snapshot isolation, and the global logical clock

How MongoDB balances performance vs consistency

Best practices to avoid slow or long-running transactions

When to use (and when NOT to use) multi-document transactions

🎯 Who This Is For:

Backend & database engineers

System design interview preparation

Engineers working on fintech or distributed systems
