Many people don’t recommend making wheels, but I don’t. I built the wheel not to use it in a production environment, but to deepen my understanding. Why not? I personally think that making wheels is almost the best way to learn, if not even one. Because making a wheel requires doing at least the following […]

Spring’s own thread pool ThreadPoolTaskExecutor
Spring default thread pool simpleAsyncTaskExecutor The interface class of Spring asynchronous thread pool is TaskExecutor, which is essentially java.util.concurrent.Executor. If there is no configuration, simpleAsyncTaskExecutor is used by default. @Async demonstrates Spring’s default simpleAsyncTaskExecutor @Component @EnableAsync public class ScheduleTask {<!– –> SimpleDateFormat sdf = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”); @Async @Scheduled(fixedRate = 2000) public void testScheduleTask() {<!– […]
“Multi-threading Killer” Python concurrent programming tool: ThreadPoolExecutor allows you to easily start multiple threads at one time and kill a large number of tasks instantly!
As program complexity and data volume continue to increase, traditional synchronous programming methods can no longer meet the needs of developers. Asynchronous programming emerged, providing higher concurrency performance and better resource utilization. Python’s concurrent.futures module is a good asynchronous programming tool. It provides a set of interfaces for convenient concurrent programming. Python already has the […]
ThreadPool thread pool
ThreadPool thread pool Why use thread pool Example Ten years ago, single-core CPU computers had fake multi-threading, like a circus clown playing with multiple balls, and the CPU needed to switch back and forth. Nowadays, it is a multi-core computer. Multiple threads run on independent CPUs, which is more efficient without switching. Advantages of thread […]

Threadpool based on C++11, simple and can take any number of parameters
Reprinted from https://www.cnblogs.com/lzpong/p/6397997.html Ahem. C++ 11 added the thread library, bidding farewell to the history of the standard library not supporting concurrency. However, C++’s support for multi-threading is still relatively low-level, and slightly more advanced usage needs to be implemented by yourself, such as thread pools, semaphores, etc. Thread pool has been asked many times […]
[java] Use of java thread pool ThreadPoolExecutor
When parsing data in Kafka, due to the large amount of data, multi-thread processing can be enabled in Java. The ThreadPoolExecutor used here can be used directly. Table of Contents 1. What is the role of the thread pool? 2. Benefits of using thread pool 3. Thread pool implementation principle 1. Thread pool processing process […]
Meituan Dynamics ThreadPoolExecutor underlying implementation source code actual combat
Opening: Introducing springboot to connect nacos to implement dynamic thread pool. Nacos must be installed at the same time. At the same time, the code will have two modules, dtp-spring-boot-starter and user module. The former will be an independent dynamic thread pool. , which can be introduced into your own project. The latter module is […]
ScheduledThreadPool principle code
ScheduledThreadPool is a thread pool used to perform scheduled tasks. It is implemented based on ThreadPoolExecutor and has some special scheduling functions. The following is the code for its implementation principle: public class ScheduledThreadPoolExecutor extends ThreadPoolExecutor implements ScheduledExecutorService {<!– –> // Scheduled task queue private final DelayedWorkQueue delayedQueue = new DelayedWorkQueue(); // Scheduled task thread […]
Concurrent programming-analysis of the underlying principles of thread pool ThreadPoolExecutor (1)
Question: How to set the number of core threads and the maximum number of threads in the thread pool? What is the specific process of thread pool execution tasks? How do the five states of the thread pool flow? How are threads in the thread pool closed? Why does the thread pool have to be […]
