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 […]

“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 […]

[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 […]
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 […]
How to elegantly customize the ThreadPoolExecutor thread pool
Hello, I am a passerby. For more high-quality articles, please see my personal blog: http://itsoku.com 1. Overview Multi-threading is often needed in Java to handle some businesses. It is highly not recommended to simply inherit Thread or implement the Runnable interface to create threads, as this will inevitably involve creation and destruction. Threads consume resources […]
A simple explanation of ThreadPoolExecutor (1)
Article directory Thread pool brief complaint Detailed explanation of ThreadPoolExecutor Detailed explanation of ThreadPoolExecutor parameters Tool class Executors for creating thread pools Task rejection policy Thread pool brief complaint For various pools, such as Connection pool: used to manage and reuse database connections to avoid the performance overhead caused by frequent creation and destruction of […]
Use ThreadPoolExecutor to manage thread pools
Use ThreadPoolExecutor to manage thread pools In multi-threaded programming, the thread pool is a key tool that can effectively manage the life cycle of threads and improve program performance and resource utilization. Java provides a powerful thread pool implementation called ThreadPoolExecutor. 1. Introduce ThreadPoolExecutor ExecutorService executor = new ThreadPoolExecutor( corePoolSize, // Number of core threads […]
In-depth anatomy of thread pool (ThreadPoolExecutor)
Directory 1 Thread Pool (ThreadPoolExecutor) 2 Use of thread pool (Executors) 2.1 newFixedThreadPool 2.2 newCachedThreadPool 2.3 newSingleThreadExecutor 2.4 newScheduledThreadPool In multi-threaded applications, the creation and destruction overhead of threads is relatively high. Every time a thread is created, the operating system needs to allocate resources, and destroying a thread also needs to release resources. The […]
