This article details the five‑year evolution of a commercial advertising platform, the performance and architectural challenges it faced, the step‑by‑step Go‑based microservice reconstruction, and the resulting tenfold improvements in capacity, latency, and cost efficiency.
This article presents a comprehensive study of local vector retrieval optimization, covering memory‑based filtering techniques, Redis‑backed vector storage designs, and various sorting algorithms—including radix and heap‑based approaches—to achieve lower latency and higher throughput for large‑scale ad recommendation systems.
The article explains consistent hashing—using a circular 2^32 hash ring with virtual nodes to evenly distribute keys across dynamic cache servers—provides a complete Go implementation including host registration, key lookup, and a bounded‑load extension that tracks server load, demonstrates a proxy‑cache setup, and discusses practical testing and production‑grade enhancements.
This article explains how improper use of database connection pools can cause service timeouts, demonstrates with Go and MySQL how to configure and test connection pooling, shows performance improvements through reuse, and encourages developers to implement their own pools for better efficiency.
This article explains Nginx’s basic round‑robin and weighted round‑robin load‑balancing algorithms, compares their characteristics, and provides complete Go implementations—including configuration snippets, core structs, and test code—to help developers integrate efficient request distribution into their backend services.
This article presents a comprehensive design and implementation of a drag‑and‑drop, code‑less workflow orchestration system that abstracts business logic into DAG‑based state machines, detailing architecture, core data structures, Go code examples, and two practical use cases for arithmetic and data‑consumption scenarios.
This article presents a code-less business process orchestration framework that transforms static Go code into configurable drag‑and‑drop workflows, detailing the underlying concepts, architecture, core Go data structures, dynamic configuration, and practical deployment examples for distributed task scheduling and execution.
This article introduces the testing pyramid, explains unit testing concepts, and provides a step‑by‑step guide for writing Go unit tests using the standard testing package, the AAA pattern, Testify assertions, mocks, and test suites, while highlighting the benefits of fast verification, documentation, and sustainable development.
This article shares practical insights on why engineers and leaders must conduct code reviews, identifies common causes of poor code such as duplication and premature decisions, and presents concrete design principles—including simplicity, composition, transparency, and disciplined logging—illustrated with Go code examples to help teams build maintainable, high‑quality backend systems.
Quick-Debug provides a lightweight solution for developers to instantly debug applications running in Kubernetes by uploading compiled binaries directly to pods via a NodePort service, eliminating the need for repeated image rebuilds and deployments.
