🧩 Replication

Keeping a copy of the same data on multiple nodes.

🎯 Mastery Criteria

Student can predict the behavior of a system during 'Split Brain' or 'Leader Failure'.
🤔 Reflection:
"If we use asynchronous replication for performance, what trade-off have we made regarding the 'Three-Legged Stool' (Reliability vs Consistency)?"

⚠️ Common Trap

Replication is instantaneous (ignoring Replication Lag).
