Class Method Details

.bigquery(project_id = nil, credentials = nil, scope: nil, retries: nil, timeout: nil) ⇒ Google::Cloud::Bigquery::Project

Creates a new Project instance connected to the BigQuery service. Each call creates a new connection.

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

Examples:

require "google/cloud"

bigquery = Google::Cloud.bigquery
dataset = bigquery.dataset "my_dataset"
table = dataset.table "my_table"

Parameters:

  • project_id (String) (defaults to: nil) —

    Identifier for a BigQuery project. If not present, the default project for the credentials is used.

  • credentials (String, Hash, Google::Auth::Credentials) (defaults to: nil) —

    The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Google::Cloud::Bigquery::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 scope is:

    • https://www.googleapis.com/auth/bigquery
  • retries (Integer) (defaults to: nil) —

    Number of times to retry requests on server error. The default value is 5. Optional.

  • timeout (Integer) (defaults to: nil) —

    Default timeout to use in requests. Optional.
