Class Method Details

.big_query_read(version: :v1, &block) ⇒ BigQueryRead::Client

Create a new client object for BigQueryRead.

By default, this returns an instance of Google::Cloud::Bigquery::Storage::V1::BigQueryRead::Client for version V1 of the API. However, you can specify specify a different API version by passing it in the version parameter. If the BigQueryRead service is supported by that API version, and the corresponding gem is available, the appropriate versioned client will be returned.
