Java Virtual Threads: Can They Handle Thousands of Concurrent Requests?
Traditional threads vs virtual threads: How Java 21 changed concurrency and how Spring Boot developers can use them in real-world applications.
Imagine an e-commerce application during a festival sale.
Thousands of customers are accessing the application at the same time.
Some customers are checking products. Others are placing orders, checking payments, and tracking deliveries.
Every request reaches the backend application.
The backend needs to process these requests, communicate with databases, call external APIs, and return responses.
Now imagine that thousands of requests arrive simultaneously.
Can a traditional Java application handle all of them efficiently?
This is where developers start thinking about thread pools, concurrency, asynchronous processing, and application performance.
Java 21 introduced an important feature that changes how developers can approach this problem: Virtual Threads.
In this article, we will understand virtual threads, compare them with traditional platform threads, build…
