Database Migration API C++ Client Library

An idiomatic C++ client library for the Database Migration API, a service to Manage Cloud Database Migration Service resources on Google Cloud Platform.

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


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

#include "google/cloud/datamigration/v1/data_migration_client.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;

  namespace datamigration = ::google::cloud::datamigration_v1;
  auto client = datamigration::DataMigrationServiceClient(

  auto const parent =
      std::string{"projects/"} + argv[1] + "/locations/" + argv[2];
  for (auto r : client.ListMigrationJobs(parent)) {
    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;
