Beschreibung
BigQuery supports both the InsertJob RPC (with type QueryJob) as well as a Query RPC (https://github.com/googleapis/googleapis/blob/8798ceff3f6fbcdce3186b67ce9339df337569d5/google/cloud/bigquery/v2/job.proto#L117). InsertJob is an asynchronous RPC stores the query results in a BigQuery table, while Query is a synchronous RPC that returns the first page of results immediately while executing a QueryJob asynchronous for the rest of the results.
Add a Query method that returns the first page of results as a collection of std::tuples and a JobReference that can be used to poll for the remainder of the results.
