Research on Implementation Approaches for Delay Queue

This paper aims to explore and compare different implementation approaches for delay queue, which enjoy widespread applications in various scenarios that require the processing of delayed tasks, such as timed task scheduling and order timeout handling. As a special data structure, delay queue is widely used in various scenarios that require the processing of delayed tasks. This paper takes the order payment functionality of e-commerce platforms as a case study, exploring various implementation strategies for delay queues, including Delay Queue, Quartz, and Redis Sorted Set. Through comparative experiments, the paper analyzes the performance, reliability, and scalability of these methods and proposes corresponding improvement suggestions based on practical application scenarios. The research findings indicate that the selection of delay queue implementation methods should be comprehensively considered based on specific requirements, system architecture, and performance requirements. This study provides valuable references and insights for the implementation and application of delay queue.
