C++

如需了解如何安装和使用 Bigtable 客户端库，请参阅 Bigtable 客户端库。

如需向 Bigtable 进行身份验证，请设置应用默认凭据。 如需了解详情，请参阅为本地开发环境设置身份验证。

namespace cbt = ::google::cloud::bigtable;
namespace cbta = ::google::cloud::bigtable_admin;
using ::google::cloud::StatusOr;
[](cbta::BigtableInstanceAdminClient instance_admin,
   std::string const& project_id, std::string const& instance_id,
   std::string const& cluster_id) {
  std::string cluster_name =
      cbt::ClusterName(project_id, instance_id, cluster_id);
  StatusOr<google::bigtable::admin::v2::Cluster> cluster =
      instance_admin.GetCluster(cluster_name);
  if (!cluster) throw std::move(cluster).status();
  std::cout << "GetCluster details : " << cluster->DebugString() << "\n";
}
