Focused on Java interview questions and practical article sharing, covering algorithms, databases, Spring Boot, microservices, high concurrency, JVM, Docker containers, and ELK-related knowledge. Looking forward to progressing together with you.
Kiwi, Alibaba’s open‑source i18n framework, offers an end‑to‑end workflow—from one‑click Chinese string extraction and linting to translation export, auto‑translation, and seamless import—addressing the searchability, missing‑string, and UI‑adjustment challenges that existing i18n libraries leave unresolved.
RedisInsight is a visual GUI for Redis that uniquely supports Redis Cluster, offers SSL/TLS connections, memory analysis and an integrated CLI; the article walks through downloading the package, configuring environment variables, starting the service on Linux, deploying it on Kubernetes with a YAML manifest, and using the UI to monitor and operate Redis instances.
This guide walks through installing ZLMediaKit via Docker, setting up FFmpeg, configuring a Spring Boot backend with streaming services, and using a simple HTML player with flv.js to push and play local video streams over RTMP.
The article defines data skew as an uneven key distribution after shuffle that makes a few tasks handle most of the data, explains the resulting slowdown, OOM, low resource utilization and job failure, and then details diagnosis methods and concrete solutions for group‑by, join, null‑value and framework‑level scenarios.
This guide walks through deploying OnlyOffice, wiring a Vue front‑end with Element UI, implementing Spring Boot back‑end endpoints to load, edit, and save Word documents, handling token verification, and troubleshooting common deployment and configuration issues.
The article explains why Druid connection pools can fail in production and provides a step‑by‑step guide to extreme optimization, covering environment setup, core pool parameter tuning, monitoring with StatFilter and web UI, security hardening, leak detection, dynamic adjustments, and common pitfalls.
The article outlines six major challenges introduced by database sharding—cross‑database joins, pagination, distributed transactions, global ID generation, data migration, and aggregation—along with practical solutions such as binding tables, cursor pagination, Seata AT mode, Snowflake IDs, dual‑write scaling, and summary tables, providing interview‑ready answers.
The article explains the differences between database sharding, table sharding, and combined sharding, outlines interview expectations, details vertical and horizontal splitting strategies, discusses when to apply each technique, and reviews practical tools such as ShardingSphere and MyCat for Java projects.
Ant Group has open‑sourced Jeandle, a new LLVM‑powered JIT compiler for the OpenJDK HotSpot JVM that promises to boost Java performance, explains JIT and LLVM fundamentals, and outlines a detailed roadmap toward full bytecode support and advanced optimizations.
The article explains why Netty outperforms raw JDK NIO for network programming by detailing NIO's pain points, Netty's elegant Reactor design, zero‑copy and memory‑pool optimizations, built‑in codecs and pipeline, bug fixes, and its extensive ecosystem, all framed as interview knowledge.
