Batch API C++ Client Library
An idiomatic C++ client library for the Batch API, a fully managed service to schedule, queue, and execute batch jobs on Google's infrastructure.
Quickstart
The following shows the code that you'll run in the google/cloud/batch/quickstart/
directory, which should give you a taste of the Batch API C++ client library API.
#include "google/cloud/batch/v1/batch_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 region-id\n";
return 1;
}
auto const location = google::cloud::Location(argv[1], argv[2]);
namespace batch = ::google::cloud::batch_v1;
auto client = batch::BatchServiceClient(batch::MakeBatchServiceConnection());
for (auto j : client.ListJobs(location.FullName())) {
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 batch_v1::BatchServiceClient
. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock batch_v1::BatchServiceClient
when testing your application.
