**APIs profiled:** 3

Google Cloud Datastore is a fully managed, schemaless, highly scalable NoSQL document database for web and mobile applications, originally based on Google's Bigtable / Megastore stack. The service has since been rebranded as Firestore in Datastore mode, which preserves the Datastore API and data model while running on Firestore's storage layer for strong consistency and higher throughput. The Cloud Datastore REST API provides entity lookups, queries (including GQL), transactions, and project operations against datastore.googleapis.com, authenticated with Google OAuth 2.0 / service-account credentials.
