Course Introduction：1. Signal synchronization and multi-threading are often collaborative operations. For example, four threads collect statistics on e-commerce data quarterly. After the statistics are completed, they are summarized. How to know that all four threads have been executed? We can use the auxiliary classes CountDownLatch (reduce count), CyclicBarrier (cyclic barrier), and Semaphore (semaphore) provided to us by JDK1.5. 2. Based on the time dimension 1. CountDownLatch depends on how many cooperating threads there are to initialize CountDownLatch's construction parameters. publicstaticvoidmain(String[]args)throwsInterruptedEx

Course Introduction：The Swoole Client class is used to implement client functions and adds asynchronous non-blocking mode, allowing users to use event loops on the client side. As a client, Swoole Client can be used in FPM environment or Apache, but Async asynchronous mode is not allowed, and only synchronous non-blocking mode can be used.

Course Introduction：Using asynchronous requests in ThinkPHP6 In the development of web applications, it is often necessary to use asynchronous requests. Asynchronous requests can be executed in the background without interfering with other operations on the page, improving the user experience. The ThinkPHP6 framework also provides a convenient asynchronous request method. This article will introduce in detail how to use asynchronous requests in ThinkPHP6. AJAX asynchronous requests can use AJAX (Asynchronous JavaScript and XML) technology

Course Introduction：How to use Redis to achieve distributed data synchronization With the development of Internet technology and the increasingly complex application scenarios, the concept of distributed systems is increasingly widely adopted. In distributed systems, data synchronization is an important issue. As a high-performance in-memory database, Redis can not only be used to store data, but can also be used to achieve distributed data synchronization. For distributed data synchronization, there are generally two common modes: publish/subscribe (Publish/Subscribe) mode and master-slave replication (Master-slave).

Course Introduction：Preface Synchronous Programming: In synchronous programming, tasks are executed one at a time, and only when one task is completed, the next task will be unblocked. Asynchronous Programming: In asynchronous programming, multiple tasks can be performed simultaneously. You can move to another task before the previous task is completed. In SpringBoot, we can use the @Async annotation to implement asynchronous behavior. Implementation steps 1. Define an asynchronous service interface AsyncService.javapublicinterfaceAsyncService{voidasyncMethod()throwsInterruptedException;FuturefutureMethod(
