auto client = milvus::MilvusClientV2::Create();

milvus::ConnectParam connect_param{"http://localhost:19530", "root:Milvus"};
auto status = client->Connect(connect_param);
if (!status.IsOk()) {
    std::cout << status.Message() << std::endl;
}

milvus::MilvusClientV2SessionPtr session;
status = client->Session(cluster_id, session);
if (!status.IsOk()) {
    std::cout << status.Message() << std::endl;
