How was multithreading implemented and designed in your previous project?

In my previous project, multithreading was implemented using the standard C++11 library (std::thread, std::mutex, std::condition_variable). The architecture involved dividing tasks into multiple threads for parallel data processing, for example, one thread was responsible for receiving and parsing incoming messages, while another handled processing and database writing.

Synchronization was achieved using mutexes and condition variables to prevent data races and ensure correct information exchange between threads. A blocking queue was also used for task transfer between threads.

Example of creating and starting a thread:

#include <thread>
#include <iostream>

void worker() {
    std::cout << "Work in a separate thread" << std::endl;
}

int main() {
    std::thread t(worker);
    t.join(); // wait for thread to finish
    return 0;
}

This approach allowed efficient use of CPU resources and provided application scalability.
