Cloud Scheduler API C++ Client Library
An idiomatic C++ client library for Cloud Scheduler, a service that creates and manages jobs run on a regular recurring schedule.
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/scheduler/quickstart/
directory, which should give you a taste of the Cloud Scheduler API C++ client library API.
#include "google/cloud/scheduler/v1/cloud_scheduler_client.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;
}
namespace scheduler = ::google::cloud::scheduler_v1;
auto client = scheduler::CloudSchedulerClient(
scheduler::MakeCloudSchedulerConnection());
auto const parent =
std::string{"projects/"} + argv[1] + "/locations/" + argv[2];
for (auto j : client.ListJobs(parent)) {
if (!j) throw std::move(j).status();
std::cout << j->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 scheduler_v1::CloudSchedulerClient
. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock scheduler_v1::CloudSchedulerClient
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.
