About this Hands-on Lab

Data comes in all shapes, sizes, and use cases. A relational database service like Cloud SQL isn’t always the answer. Cloud Datastore is a NoSQL database service, ideal for semi-structured data that needs to be highly scalable and available. Cloud Firestore is the next generation of Datastore with enhanced features, and in this hands-on lab, you’ll see how to build a Firestore NoSQL database in Cloud Datastore mode for the best of both worlds.
