Cloud Firestore API - Module Google::Cloud::Firestore (v2.16.0)

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.

Methods

.configure

def self.configure() -> Google::Cloud::Config

Configure the Google Cloud Firestore library.

The following Firestore configuration parameters are supported:

  • project_id - (String) Identifier for a Firestore project. (The parameter project is considered deprecated, but may also be used.)
  • credentials - (String, Hash, Google::Auth::Credentials) The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials) (The parameter keyfile is considered deprecated, but may also be used.)
