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

Methods

.spanner

def self.spanner(project_id = nil, credentials = nil, scope: nil, timeout: nil, lib_name: nil, lib_version: nil) -> Google::Cloud::Spanner::Project

Creates a new object for connecting to the Spanner service. Each call creates a new connection.

For more information on connecting to Google Cloud see the Authentication Guide.

Parameters

project_id (String) — Project identifier for the Spanner service you are connecting to. If not present, the default project for the credentials is 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 Spanner::Credentials)
scope (String, Array<String>) (defaults to: nil) —
The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

The default scopes are:
- https://www.googleapis.com/auth/spanner
- https://www.googleapis.com/auth/spanner.data
timeout (Integer) (defaults to: nil) — Default timeout to use in requests. Optional.
lib_name (String) (defaults to: nil) — Library name. This will be added as a prefix to the API call tracking header x-goog-api-client with provided lib version for telemetry. Optional. For example prefix looks like spanner-activerecord/0.0.1 gccl/1.13.1. Here, spanner-activerecord/0.0.1 is provided custom library name and version and gccl/1.13.1 represents the Cloud Spanner Ruby library with version.
lib_version (String) (defaults to: nil) — Library version. This will be added as a prefix to the API call tracking header x-goog-api-client with provided lib name for telemetry. Optional. For example prefix look like spanner-activerecord/0.0.1 gccl/1.13.1.
