system-design

System Design is a Chinese-language collection of detailed solutions to classic architecture interview problems. It teaches readers how to break broad product requirements into components, data flows, storage choices, scaling strategies, and operational tradeoffs. The examples cover URL shortening, news feeds, search engines, crawlers, key-value stores, distributed identifiers, task schedulers, file-system caches, and load balancers. Additional material discusses API rate limiting, hash maps, PageRank, frequent-item analysis, and big-data scenarios. The repository presents each case as a focused Markdown chapter with diagrams and supporting explanations. A methodology chapter helps readers apply a repeatable approach instead of memorizing isolated answers. The content can be read online as a GitBook and is published under a shareable Creative Commons license.
