Question

You are designing a Node.js-based mobile news feed application that stores data on Google Cloud. You need to select the application's database. You want the database to have zonal resiliency out of the box, low latency responses, ACID compliance, an optional middle tier, semi-structured data storage, and network-partition-tolerant and offline-mode client libraries. What should you do?

Accepted Answer
