Cloud Memorystore for Memcached API C++ Client Library

An idiomatic C++ client library for the Cloud Memorystore for Memcached API, a service for creating and managing Memcached instances in GCP.

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/memcache/quickstart/ directory, which should give you a taste of the Cloud Memorystore for Memcached API C++ client library API.

#include "google/cloud/memcache/v1/cloud_memcache_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;

  auto const location = google::cloud::Location(argv[1], "-");

  namespace memcache = ::google::cloud::memcache_v1;
  auto client =

  for (auto i : client.ListInstances(location.FullName())) {
    if (!i) throw std::move(i).status();
    std::cout << i->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 memcache_v1::CloudMemcacheClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock memcache_v1::CloudMemcacheClient when testing your application.
