Cloud Data Fusion API C++ Client Library (original) (raw)

Cloud Data Fusion API C++ Client Library

An idiomatic C++ client library for the Cloud Data Fusion API, a fully-managed, cloud native, enterprise data integration service for quickly building and managing data pipelines.

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

Quickstart

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

#include "google/cloud/datafusion/v1/data_fusion_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
    return 1;
  }

  auto const location = google:☁️:Location(argv[1], argv[2]);

  namespace datafusion = ::google:☁️:datafusion_v1;
  auto client =
      datafusion::DataFusionClient(datafusion::MakeDataFusionConnection());

  for (auto av : client.ListAvailableVersions(location.FullName())) {
    if (!av) throw std::move(av).status();
    std::cout << av->DebugString() << "\n";
  }

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

Main classes

The main class in this library is datafusion_v1::DataFusionClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock datafusion_v1::DataFusionClient when testing your application.
