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 notfollow Semantic Versioning .

Quickstart

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/project.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " project-id\n";
    return 1;
  }

  namespace memcache = ::google::cloud::memcache_v1;
  auto client =
      memcache::CloudMemcacheClient(memcache::MakeCloudMemcacheConnection());

  auto const project_id = std::string(argv[1]);
  auto const parent = "projects/" + project_id + "/locations/-";
  for (auto r : client.ListInstances(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 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.

Retry, Backoff, and Idempotency Policies.

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.
