SystemDesignPlayground

A playground and centralized repository for system design concepts, frameworks, and detailed architectural implementations. This project combines Java-based design examples with comprehensive documentation for real-world system design interview problems.

📁 Repository Structure

The repository is structured to include both structural frameworks and individual system architectures:

├── src/main/java/code/example/          # Java implementations of system design concepts
├── instagram_timeline_feed_design.md    # Architecture and design for an Instagram-like feed
├── personalized_google_feed_design.md   # Design for a personalized, high-scale Google Feed
├── rate_limiter_system_design.md        # Deep dive into designing a scalable Rate Limiter
├── system_design_interview_framework.md # A step-by-step framework to tackle system design interviews
├── build.gradle                         # Gradle build configuration
└── settings.gradle                      # Gradle project settings

✨ Features & Deep Dives

• Comprehensive Framework: A structured approach to breaking down complex system design interview questions (system_design_interview_framework.md).
• Real-World System Architectures: End-to-end designs covering data flow, database choices, scalability, and bottlenecks for:
  • Instagram Timeline Feeds
  • Personalized Google Feeds
  • Distributed Rate Limiters
• Code Implementations: Hands-on Java examples representing design patterns and software architectural components under src/main/.

💻 Usage

Reading the Design Docs

You can read through the markdown files directly on GitHub or using any markdown viewer to study the system design breakdowns.

Running Java Examples

To execute or run tests on the Java components within the playground:

./gradlew run

(Alternatively, you can import this directory directly into IntelliJ IDEA or Eclipse as a Gradle project).
