C++ 빅데이터 개발 시 데이터 손실 문제를 어떻게 처리하나요?

#include <memory>

int main() {
    // 动态分配内存
    std::unique_ptr<int> ptr = std::make_unique<int>(10);

    // 使用智能指针管理内存
    std::shared_ptr<int> sharedPtr = std::make_shared<int>(20);

    // 显式释放内存
    ptr.reset();
    sharedPtr.reset();

    return 0;
}

#include <iostream>

int main() {
    try {
        // 数据处理逻辑
        
        // 发生异常时进行处理
    } catch (const std::exception& e) {
        std::cerr << "Error: " << e.what() << std::endl;
        // 异常处理逻辑
    }

    return 0;
}

#include <iostream>
#include <fstream>

void backupData(const std::string& data) {
    std::ofstream backupFile("backup.txt");
    backupFile << data;
    backupFile.close();
}

bool validateData(const std::string& data) {
    // 计算数据校验值并与原校验值比较
}

int main() {
    std::string data = "This is a test data";
    
    // 数据备份
    backupData(data);
    
    // 数据校验
    if (validateData(data)) {
        std::cout << "Data is valid" << std::endl;
    } else {
        std::cout << "Data is invalid" << std::endl;
        // 使用备份数据进行恢复
    }

    return 0;
}

#include <iostream>
#include <boost/asio.hpp>

void sendData(boost::asio::ip::tcp::socket& socket, const std::string& data) {
    boost::asio::write(socket, boost::asio::buffer(data));
}

std::string receiveData(boost::asio::ip::tcp::socket& socket) {
    boost::asio::streambuf buffer;
    boost::asio::read(socket, buffer);
    std::string data((std::istreambuf_iterator<char>(&buffer)),
                     std::istreambuf_iterator<char>());
    return data;
}

int main() {
    boost::asio::io_context ioContext;
    boost::asio::ip::tcp::socket socket(ioContext);

    // 进行数据传输
    std::string data = "This is a test data";

    sendData(socket, data);
    std::string receivedData = receiveData(socket);

    std::cout << "Received data: " << receivedData << std::endl;

    return 0;
}
