Design a Real-Time Sports Scoring System

Functional Requirements:

• Provide real-time updates for sports scores and key game events (e.g., goals, fouls, timeouts).
• Display live scores, team names, and game status on a scoreboard interface.
• Track and show player statistics (e.g., goals, assists, fouls) during games.
• Maintain a timeline of game events for each match.
• Support user access to live scores and statistics via web/mobile clients.
• Allow users to set preferences (e.g., favorite teams) and receive notifications for major events.
• Ingest live data from external sports data providers.

Non-Functional Requirements:

• Low latency: Updates should be reflected to users within 1-2 seconds of the event.
• Scalability: System should support up to 1 million concurrent users during peak events.
• High availability: Service should be resilient to failures and minimize downtime.
• Security: Protect user data and prevent unauthorized access.
• Usability: Interfaces should be simple and responsive across devices.
• Maintainability: System should be easy to update and extend for new sports or features.
