Kujiale Technology Quality
This article outlines the background, analysis, design, testing strategy, migration plan, and production quality results for implementing horizontal sharding, table splitting, and Elasticsearch integration in a growing enterprise database system.
This article details a real‑world multi‑cloud cluster migration, covering preparation, testing strategies, traffic replay, performance validation, latency simulation, and communication practices that enabled a successful two‑hour cutover without impacting critical services.
This article explains how the Apollo testing framework was redesigned to enable scenario‑based API testing, reduce case creation and maintenance costs, improve quality checks, and support advanced features like traffic replay, ultimately enhancing automation efficiency for large‑scale business services.
This case study describes how a rendering middle‑platform team tackled complex micro‑service chains, inconsistent data rules, and massive 3D data to create a full‑link location and visualization platform that enables self‑service debugging, reduces developer effort by over 30 %, and serves more than 170 monthly users.
This article outlines systematic methods for diagnosing subtle performance issues by leveraging detailed data analysis of CPU, memory, disk I/O, and network metrics, and presents real-world case studies that demonstrate how targeted profiling and optimization can reveal and resolve hidden bottlenecks in complex systems.
This article outlines a comprehensive, step‑by‑step approach for migrating massive tables—up to billions of rows—through sharding, dual‑write, data synchronization, validation, testing, and controlled switch‑over to ensure minimal impact on production services.
This article details a four‑stage migration project that rebuilt international services on a cloud‑native stack, introducing temporary Istio monitoring, standardized change processes, Helm‑based deployments, and full microservice integration while sharing practical quality‑assurance lessons and pitfalls.
This article explains why data exchange between numerous frontend plugins in large‑scale applications is hard to trace, reviews common debugging techniques, adapts backend tracing ideas, and presents a concrete implementation for retrieving and validating plugin data in real time.
This article explains why mesh regression is needed for 3D cloud design tools, defines mesh, outlines its application scenarios such as BIM plumbing, custom door windows, and hard‑floor tiles, and details a step‑by‑step design, implementation, bug detection methods, performance improvements, and future plans.
This article reviews the formation, strategies, and outcomes of a test‑team influence‑operations group, detailing its internal sharing events, data‑driven metrics, content review practices, promotional tactics, and lessons learned for improving team impact and productivity.
