ChronoScore

Welcome to ChronoScore, a cutting-edge real-time leaderboard system designed to handle massive scale and deliver instantaneous results. This project tackles the complex challenges of building and maintaining a high-performance leaderboard in a dynamic environment.

Overview

Designing a real-time leaderboard system is no small feat. It involves balancing performance, scalability, and data consistency. With ChronoScore, we dive deep into the intricacies of real-time data processing and present a robust solution for online platforms where user engagement and rewards drive success.

Scenario

Imagine an online gaming platform with the following requirements:

• Active Users: 50 million
• Daily Active Users: 10 million
• Leaderboard Update: Real-time or near real-time
• Data Consistency: Eventual consistency is acceptable
• Display: Top 10 users and their ranks

Our goal is to create a system that efficiently processes and displays the top performers, even under high load conditions.

System Design

Challenges

1. High Load Handling: With millions of daily active users, the system must handle a significant volume of updates and queries without performance degradation.
2. Real-Time Updates: Ensuring that the leaderboard reflects the latest user scores instantly or within a near-real-time window.
3. Scalability: The system should scale horizontally to accommodate growing user numbers and data.

Design Overview

• Database Design: We use PostgreSQL for its reliability and performance. The core tables include:

  • user_score: Stores user scores.
  • users: Contains user profile information.

  These tables are designed to support efficient querying and updates, essential for real-time operations.

• System Architecture: The architecture is optimized for high throughput and low latency, using a combination of caching, asynchronous processing, and efficient querying techniques.

Key Components

• Data Aggregation: Implemented to aggregate user scores and calculate rankings efficiently.
• Real-Time Processing: Utilizes streaming technologies and event-driven architecture to ensure timely updates.
• Scalability: Designed to scale both vertically and horizontally, adapting to varying load conditions.
