Google Cloud Data Catalog API C++ Client Library

An idiomatic C++ client library for the Google Cloud Data Catalog API, a fully managed and highly scalable data discovery and metadata management service.

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/datacatalog/quickstart/ directory, which should give you a taste of the Google Cloud Data Catalog API C++ client library API.

#include "google/cloud/datacatalog/v1/data_catalog_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::cloud::Location(argv[1], argv[2]); namespace datacatalog = ::google::cloud::datacatalog_v1; auto client = datacatalog::DataCatalogClient(datacatalog::MakeDataCatalogConnection()); for (auto eg : client.ListEntryGroups(location.FullName())) { if (!eg) throw std::move(eg).status(); std::cout << eg->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.
