BigQuery API C++ Client Library

An idiomatic C++ client library for the BigQuery API .

A data platform for customers to create, manage, share and query data.

While this library is GA, please note Google Cloud C++ client libraries do not** follow Semantic Versioning .

Quickstart

The following shows the code that you'll run in the google/cloud/bigquerycontrol/quickstart/ directory, which should give you a taste of the BigQuery API C++ client library API.

 #include "google/cloud/bigquerycontrol/v2/job_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " project-id\n";
    return 1;
  }

  auto const project_id = argv[1];

  namespace bigquerycontrol = ::google::cloud::bigquerycontrol_v2;
  namespace bigquery_v2_proto = ::google::cloud::bigquery::v2;
  auto client = bigquerycontrol::JobServiceClient(
      bigquerycontrol::MakeJobServiceConnectionRest());

  bigquery_v2_proto::ListJobsRequest list_request;
  list_request.set_project_id(project_id);

  for (auto r : client.ListJobs(list_request)) {
    if (!r) throw std::move(r).status();
    std::cout << r->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}

Main classes

This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.

The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
