This repository provides reference implementations of common system design patterns in Python and Java. It is primarily an educational resource containing standalone algorithm implementations for consistent hashing, rate limiting (token bucket, leaky bucket, sliding window variants), and load balancing algorithms (round robin, weighted round robin, least connections, least response time, IP hash). The code serves as a learning tool for system design interviews and concepts rather than a production-ready application. Each implementation is self-contained with usage examples embedded in the source files. The repository has no external dependencies beyond standard libraries, making it easy to extract and study individual patterns.
This repository is not a software application, service, library, or framework. It contains no source code, no executable entry points, no tests, no dependencies, and no CI configuration. The only substantive file is README.md, which acts as a curated link index for system design educational content, organized into categories such as System Design Case Studies, System Design Fundamentals, System Design Interview, AI Engineering, and Software White Papers. Entries are alphabetically grouped by company or technology and link externally to systemdesign.one and newsletter.systemdesign.one articles, plus a sponsored webinar banner.
