клиент ignite c ++ для интеграции cassandra

Я разрабатываю приложение для передачи данных, в котором я хочу общаться с Кассандрой через ignite c ++. когда я пытаюсь поместить данные на Кассандру, все работает нормально. но я не могу получить данные из того же.
вот мой код

test.h

namespace ignite
{
namespace examples
{
struct Test
{
Test()
{
// No-op.
}

Test(const std::string& assetid, const std::string& asset_desc, const std::string& groupid) :
assetid (assetid), asset_desc (asset_desc), groupid (groupid)
{
// No-op.
}

std::string ToString()
{
std::ostringstream oss;

oss << "Address [street=" << assetid << ", zip=" << asset_desc<< "]";

return oss.str();
}

std::string assetid;
std::string asset_desc;
std::string groupid;
};
}
}
