We try to be honest about what the product can't do natively and provide best practices, take a look at the "solutions" section of the documentation: https://firebase.google.com/docs/firestore/solutions/ https://firebase.google.com/docs/firestore/solutions/ For example Cloud Firestore can't do native full text search, but we made sure it's easy to integrate with a search provider like Algolia. As for your guess about Spanner, you're right that Cloud Firestore uses the same technology as Cloud Spanner to ensure consistency at scale. Would love to know what you think about the product once you've tried it!
