The article analyzes the requirements of a massive‑scale like feature, compares small‑scale MySQL implementations with the graph‑plus‑KV architectures used by ByteDance, Kuaishou and Xiaohongshu, and presents a practical hybrid solution based on Redis, MySQL and batch processing to handle hot content and super‑node challenges.
This article breaks down the essential requirements and architecture of a high‑performance like system, covering fast response, data consistency, scalability under traffic spikes, and cost‑efficient resource use, while detailing the technical stack, caching strategies, async persistence, and practical optimizations.
To reduce database load from high‑frequency like and favorite actions, the article outlines a backend solution that stores per‑article like data in Redis hashes, periodically synchronizes the cached data to MySQL using Quartz scheduled jobs, and shows how to indicate whether a user has liked each article.
This tutorial explains how to implement a like/unlike feature using Spring Boot, Redis caching, and periodic persistence to a database with Quartz, covering data modeling, key design, service layers, controller APIs, and scheduled synchronization.
This article analyzes common like‑system business scenarios, derives functional requirements, proposes three architectural solutions (Redis‑based priority queue, relational database, and a hybrid cache‑MQ‑DB design), presents detailed implementation code, and evaluates each approach with extensive performance tests to guide practical backend design choices.
This article explains how to use Redis bitmap operations to efficiently implement like, sign‑in, and other binary state features, covering bitmap fundamentals, common use cases, essential commands, Java code examples with Jedis, and range query techniques.
This tutorial walks through building a scalable like feature using Spring Cloud, Redis caching, MySQL persistence, and Quartz scheduling, covering Redis installation, Spring Boot integration, data modeling, service implementation, and periodic synchronization of high‑frequency like operations to the database.
This article demonstrates how to design and implement a high‑frequency like/unlike functionality in a Spring Cloud application by using Redis as a cache, persisting data to MySQL at two‑hour intervals, and automating the sync with Quartz scheduled jobs.
This article walks through designing and implementing a high‑traffic like/unlike feature for a social platform using Spring Cloud, Redis caching, MySQL persistence, and a Quartz‑based scheduled job to sync data every two hours.
This article explains how to design and implement a high‑frequency like/unlike feature for large social platforms using Spring Cloud, Redis caching, MySQL persistence, and Quartz scheduled jobs, covering Redis setup, data modeling, service interfaces, database schema, and periodic data synchronization.
The PCC (Performance Challenge Championship) was a one‑day offline competition where engineers built a high‑throughput “like” service, explored architectures such as OpenResty‑Lua, micro‑services with Go, caching strategies, and used Tsung for stress testing, with winners showcased and code released on GitHub.
