Design Amazon DynamoDB System Design Interview Question | EngMock

1. Problem Statement

Design a distributed Key-Value store that prioritizes Write Availability above everything else. E.g. the Amazon Shopping Cart service. It must never reject a write.

2. Architecture Discussion Map

Use this as one discussion aid, not a single correct answer. Your design should follow from the requirements, scale, and trade-offs you establish.
