Distributed task scheduling and distributed unique ID generation method in PHP flash sale system
Article Introduction:Distributed task scheduling and distributed unique ID generation methods in the PHP flash sale system In the PHP flash sale system, distributed task scheduling and distributed unique ID generation are two very critical functions. This article will introduce how to implement these two functions and provide specific code examples. 1. Distributed task scheduling In the flash sale system, a large number of concurrent operations and scheduled tasks are required. In a stand-alone environment, these operations and tasks will put a lot of pressure on the server. In order to improve the system's concurrent processing capabilities and task scheduling efficiency, we can use splitting

Implementation principle of consistent hash algorithm for PHP data cache
Article Introduction:Implementation Principle of Consistent Hash Algorithm for PHP Data Cache Consistent Hashing algorithm (ConsistentHashing) is an algorithm commonly used for data caching in distributed systems, which can minimize the number of data migrations when the system expands and shrinks. In PHP, implementing consistent hashing algorithms can improve the efficiency and reliability of data caching. This article will introduce the principles of consistent hashing algorithms and provide code examples. The basic principle of consistent hashing algorithm. Traditional hashing algorithm disperses data to different nodes, but when the node
