Consistency Models

Trade-offs between strong, eventual, and causal consistency.

📄️ Strong Consistency

All reads reflect the latest successful write—simpler reasoning at higher latency/cost.

📄️ Eventual Consistency

Replicas converge over time—high availability and low latency with stale‑read trade‑offs.

📄️ Causal Consistency

Preserve cause-before-effect visibility across replicas without global total order.
