| Trade‑off | Options | |-----------|---------| | | Choose based on CAP theorem – CP (strong consistency) vs. AP (high availability). | | Sync vs. Async | Use async processing (message queues, Kafka) for decoupling and resilience. | | Read‑heavy vs. Write‑heavy | Read‑heavy → cache + replicas. Write‑heavy → sharding + append‑only logs. | | Strong vs. Eventual consistency | Strong for payments, eventual for social feeds. |
