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.
Quickstart
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(
datamigration::MakeDataMigrationServiceConnection());
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;
}
Main classes
The main class in this library is datamigration_v1::DataMigrationServiceClient
. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock datamigration_v1::DataMigrationServiceClient
when testing your application.
