These are known as high-throughput applications. Imagine for example, that this type of an application has code like this. This has mainly three tasks that will be executed by threads. The second task, that sendRequest, is a network call to access an external resource. So this is a blocking I/O operation. A regular or classic Java thread that runs this type of blocking task code will be idle for some time, waiting for a response back from other servers. This is a waste of computing resources, mainly RAM and is a major barrier in achieving high throughput. Let's take a closer look at this. A classic or regular Java thread, which is more…
