Cloud Firestore API - Module Google::Cloud::Firestore (v2.7.1)

Reference documentation and code samples for the Cloud Firestore API module Google::Cloud::Firestore.

Cloud Firestore

Cloud Firestore is a NoSQL document database built for automatic scaling, high performance, and ease of application development. While the Cloud Firestore interface has many of the same features as traditional databases, as a NoSQL database it differs from them in the way it describes relationships between data objects.

See Firestore Overview.
