Class Method Details

.configure {|Google::Cloud.configure.bigquery| ... } ⇒ Google::Cloud::Config

Configure the Google Cloud BigQuery library.

The following BigQuery configuration parameters are supported:

  • project_id - (String) Identifier for a BigQuery 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.)
  • scope - (String, Array) The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access.
  • retries - (Integer) Number of times to retry requests on server error.
  • timeout - (Integer) Default timeout to use in requests.

Yields:

Returns:

  • (Google::Cloud::Config) —

    The configuration object the Google::Cloud::Bigquery library uses.

end

.new(project_id: nil, credentials: nil, scope: nil, retries: nil, timeout: nil, project: nil, keyfile: 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"

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

Parameters:

  • project_id (String) —

    Identifier for a BigQuery project. 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 Credentials)

  • scope (String, Array<String>) —

    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) —

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

  • timeout (Integer) —

    Default timeout to use in requests. Optional.

  • project (String) —

    Alias for the project_id argument. Deprecated.

  • keyfile (String) —

    Alias for the credentials argument. Deprecated.

Returns:

Raises:

  • (ArgumentError)
