An idiomatic C++ client library for the Dataproc Metastore API, a service to manage the lifecycle and configuration of metastore services.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
QuickstartThe following shows the code that you'll run in the google/cloud/metastore/quickstart/ directory, which should give you a taste of the Dataproc Metastore API C++ client library API.
#include "google/cloud/metastore/v1/dataproc_metastore_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;
}
// Use the `-` wildcard to search in all locations.
auto const location = google::cloud::Location(argv[1], "-");
namespace metastore = ::google::cloud::metastore_v1;
auto client = metastore::DataprocMetastoreClient(
metastore::MakeDataprocMetastoreConnection());
for (auto s : client.ListServices(location.FullName())) {
if (!s) throw std::move(s).status();
std::cout << s->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
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.
