Oct 6, 2011 · It can pretty much be simplified to be roughly 2000 milliseconds. If you want it to continue calling forward for 2 seconds (which would result in quite a few invocations of the function), you will need to use a timer of some sort.

In this article, we’ll learn how we can end a long-running execution after a certain time. We’ll explore the various solutions to this problem. Also, we’ll cover some of their pitfalls.
Imagine that we’re processing a bunch of items in a loop, such as some details of the product items in an e-commerce application, but that it may not be necessary to complete all the items. In fact, we’d want to process only up to a certain time, and after that, we want to stop the execution and show whatever the list has processed up to that time....
Here, we’ll use a separate thread to perform the long-running operations. The main thread will send an interrupt signal to the worker thread on timeout. If the worker thread is still alive, it’ll catch the signal and stop its execution. If the worker finishes before the timeout, it’ll have no impact on the worker thread. Let’s take a look at the wo...
There’s no guarantee that the execution is stopped after a certain time. The main reason is that not all blocking methods are interruptible. In fact, there are only a few well-defined methods that are interruptible. So, if a thread is interrupted and a flag is set, nothing else will happen until it reaches one of these interruptible methods. For ex...
In the previous section, we highlighted the importance of having interruptible methods to stop the execution as soon as possible. Therefore, our code needs to consider this expectation from a design perspective. Imagine we have a long-running task to execute, and we need to make sure it doesn’t take more time than the specified. Also, suppose the t...
In this tutorial, we’ve learned various techniques for stopping the execution after a given time, along with the pros and cons of each. The complete source code can be found over on GitHub.
Jan 23, 2017 · Each dependency call has a timeout of 100ms and the calls are made concurrently. We have 10 threads for the executor which runs these calls.

Mar 26, 2021 · Timeouts and how to handline in Java. # java # spring. In this article we will try to cover why it’s important to define timeouts for out bound rest calls. Before configuring any timeout let’s understand below some common exceptions for http outbound calls, Connection timeout.
Jan 8, 2024 · We can annotate a unit test with JUnit5’s @Timeout to specify the maximum number of seconds it can run for; if this value is exceeded, the test will fail with a java.util.concurrent.TimeoutException:

Oct 4, 2012 · You can have a look at TimeLimiter from guava that can take any class and produce time-limited proxy. But it still uses thread pool internally to wait for Future (at least the default SimpleTimeLimiter implementation).
