Overview

Google Cloud BigQuery

Google BigQuery enables super-fast, SQL-like queries against massive datasets, using the processing power of Google's infrastructure.

See BigQuery Overview.

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 - (Google::Auth::Credentials) A Google::Auth::Credentials object. (See Credentials) @note Warning: Passing a String to a keyfile path or a Hash of credentials is deprecated. Providing an unvalidated credential configuration to Google APIs can compromise the security of your systems and data.
  • 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:

  yield Google::Cloud.configure.bigquery if block_given?

  Google::Cloud.configure.bigquery
end

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

Raises:

  • (ArgumentError)
