Node.JS Express. Simultaneous requests, an opinion is required. How to be?

Question

Computer networks

I describe my problem that haunts me.
In general, I make 2 POST requests with the same data at the same time.
The server logic is such that the data in the request is unique. As a result, when sending two requests, no error occurs - this is not normal behavior, in my opinion, since both requests were successfully completed. Next, I did a sleep for 10 milliseconds, and everything began to work fine.
My concern is, is it possible to send n-th number of simultaneous requests from different users and how to prevent the same data from getting into the database?

Answer 1

Физически не возможно принять два и более запроса одновременно.
Физически не возможно в одном инстансе ноды одновременно их принять из сокета.
Как правильно написали - в очередь, или базу точить (фактически база будет очередью).

Answer 2

Думаю, нужно использовать очереди. Обрати внимание на RabbitMQ

Answer 3

Куда они записываются ?
