This article introduces Alibaba's JetCache Java caching framework, explains how to integrate it with Spring Boot and Redis, provides detailed configuration and code examples for local, remote, and multi‑level caches, and covers testing procedures and common error resolutions.
This article introduces Alibaba's JetCache framework, explains how to configure and combine local and remote (Redis) caches in a Spring Boot project, and demonstrates three usage patterns—AOP annotations, API mode, and advanced CacheManager API—along with troubleshooting tips and test procedures.
This tutorial walks through the evolution from manual Redis calls to Spring Cache abstraction, explains AOP‑based proxying, details core annotations, demonstrates Caffeine and Redisson integration, explores list caching, and shows how to build a custom two‑level cache for high‑performance Java back‑ends.
This article explains the fundamentals of caching, why caches (especially Redis) are essential for high‑performance and high‑concurrency scenarios, compares local, distributed, and multi‑level caches, and outlines their advantages, disadvantages, and typical implementation approaches.
This article explains the fundamentals of caching, why caches (especially Redis) are essential for high‑performance and high‑concurrency scenarios, describes local, distributed, and multi‑level cache architectures, outlines their pros and cons, and provides practical implementation guidance.
This article explains the fundamentals of caching, why caches like Redis are essential for high‑performance and high‑concurrency backend systems, and compares local, distributed, and multi‑level cache architectures, including their advantages, drawbacks, and typical implementation approaches.
This article walks through adapting a custom Redis client to Spring Cache, explains the cache abstraction, demonstrates annotation‑driven caching, shows how to integrate Caffeine and Redisson, and builds a simple two‑level cache to illustrate advanced scenarios for Spring Cache users.
This guide explains caching fundamentals, purposes, and optimal use cases, details hit rates and eviction policies such as FIFO, LRU, LFU, TTL/TTI, compares client‑side (HTTP, browser) and server‑side caches (CDN, Redis, Memcached), explores multi‑level architectures, common pitfalls like avalanche, penetration and breakdown, and best‑practice strategies including pre‑warming, update patterns, and consistency management.
Server‑side caching improves performance by trading space for time, using local caches like HashMap, Guava, Ehcache, and Caffeine, distributed caches such as Redis, and multi‑level architectures that combine in‑process, distributed, and database layers, while employing consistency patterns, monitoring, and hot‑key detection.
This article shares a decade of practical experience with caching, covering local page and object caches, distributed solutions like Redis and Memcached, pagination caching techniques, multi‑level cache architectures, refresh mechanisms, and lessons learned from real‑world performance optimizations.
This article explores multi‑level caching architectures, detailing how Nginx, local and distributed caches, and Tomcat interact, and offers practical solutions for expiration strategies, dimensional caching, load‑balancing algorithms, hot‑data handling, atomic updates, and rapid recovery from cache failures.
