Analysis of low delayed original concurrent queue architecture technical analysis in the java class library Summary: The low -delayed original concurrent queue is of great significance in high concurrent scenes.This article will introduce the low -delayed original concurrent queue architecture technology in the Java class library, focusing on its implementation principles, characteristics, and usage scenarios, and providing related Java code examples. introduction: When dealing with high concurrent tasks, the queue is a commonly used data structure to solve the asynchronous communication problem between producers and consumers.However, most queues usually have high delay in high concurrency environments, and in the most extreme cases, resource competition and performance decline.In order to solve these problems, the Java library provides a low -delayed primitive concurrent queue architecture. 1. The concept of the original concurrent queue The original concurrent queue is a data structure in the Java class library, which is used to provide low -delay asynchronous communication in a high concurrency environment.Unlike the traditional blocking queue, the primitive concurrent queue will not introduce obstruction operations when entering the team or departing, thereby greatly reducing the waiting time of the thread. 2. Principles of the original concurrent queue The implementation principle of the original concurrency queue is mainly based on the following two core concepts: a. No lock algorithm: The original concurrent queue uses lock -free algorithms to achieve efficient concurrent operations.It uses atomic operations based on CAS (Compaare and Swap) to achieve unlocked concurrency control, avoiding the performance bottleneck and resource competition introduced by the traditional lock mechanism. b. Lock separation technology: The original concurrent queue uses different locks to use different locks to achieve lock separation by using different locks.This can improve the concurrency and reduce the occurrence of locking. 3. The characteristics of the original concurrent queue Low latency original concurrent queue has the following characteristics: a. High -efficiency: The use of lock -free algorithm and lock separation technology reduces resource competition and performance bottlenecks, and improves concurrent performance. b. Low latency: Avoid obstructive waiting, reducing the waiting time of threads. c. Unbounded queue: Support the length of unbounded queue, there is no maximum capacity limit. d. Fairness: Support fair and non -fair task scheduling strategies. 4. The use scene of the original concurrency queue Low latency original concurrent queue is suitable for the following scenes: a. High concurrent environment: In the scenario where a large number of concurrent tasks are required, the use of low delayed original concurrent queues can improve the throughput and response time of the system. b. Asynchronous communication: When the producer and consumers need to perform efficient asynchronous communication, the use of low -delayed primitive concurrent queues can reduce waiting time and improve task processing efficiency. c. High throughput task processing: For scenarios that require a large number of tasks, low -delayed original concurrent queue can effectively improve the task processing capacity and the overall performance of the system. Code example: The following is a simple Java code example, which shows how to use the original concurrent queue in the Java class library: import java.util.concurrent.ConcurrentLinkedQueue; public class ConcurrentQueueExample { public static void main(String[] args) { // Create an original concurrent queue ConcurrentLinkedQueue<String> queue = new ConcurrentLinkedQueue<>(); // Producer thread, add elements to the queue Thread producer = new Thread(() -> { for (int i = 0; i < 10; i++) { queue.offer("Element " + i); System.out.println("Producer - Added element: Element " + i); } }); // Consumer thread, take out elements from the queue Thread consumer = new Thread(() -> { while (!queue.isEmpty()) { String element = queue.poll(); System.out.println("Consumer - Consumed element: " + element); } }); // Starters and consumer threads producer.start(); consumer.start(); } } This example shows a simple producer-consumer model that uses the original concurrent queue to implement the task asynchronous communication.Producer threads are constantly adding elements to the queue, while consumer threads are constantly taking out elements from the queue for processing. in conclusion: Low delayed original concurrent queue is an important data structure provided by the Java class library that can achieve low -delay asynchronous communication in high concurrency environments.It improves concurrent performance through lock -free algorithm and lock separation technology, and is suitable for multiple scenarios such as high composite, asynchronous communication and high throughput tasks.In practical applications, developers can choose the appropriate low -delayed original concurrent queue according to specific needs to optimize and improve.
