An idiomatic C++ client library for the AlloyDB API. AlloyDB for PostgreSQL is an open source-compatible database service that provides a powerful option for migrating, modernizing, or building commercial-grade applications. It offers full compatibility with standard PostgreSQL, and is more than 4x faster for transactional workloads and up to 100x faster for analytical queries than standard PostgreSQL in our performance tests. AlloyDB for PostgreSQL offers a 99.99 percent availability SLA inclusive of maintenance.
AlloyDB is optimized for the most demanding use cases, allowing you to build new applications that require high transaction throughput, large database sizes, or multiple read resources; scale existing PostgreSQL workloads with no application changes; and modernize legacy proprietary databases.
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/alloydb/quickstart/ directory, which should give you a taste of the AlloyDB API C++ client library API.
#include "google/cloud/alloydb/v1/alloy_db_admin_client.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 2) {
std::cerr << "Usage: " << argv[0] << " project-id\n";
return 1;
}
namespace alloydb = ::google::cloud::alloydb_v1;
auto client =
alloydb::AlloyDBAdminClient(alloydb::MakeAlloyDBAdminConnection());
auto const parent = std::string{"projects/"} + argv[1] + "/locations/-";
for (auto r : client.ListClusters(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;
}
The main class in this library is alloydb_v1::AlloyDBAdminClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock alloydb_v1::AlloyDBAdminClient when testing your application.
The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.
