Overview
Real-time blockchain event indexing platform with interactive analytics. Built to learn performance optimization and caching strategies at scale.
Key Features
- Real-time event indexing: Listen to blockchain events and index immediately
- LRU caching: 8-10x performance improvement with 80-90% hit rate
- High throughput: Handles 200-500 req/s with sub-200ms P95 response times
- Analytics dashboard: Player leaderboards, event distribution charts, timeline visualization
- Batch processing: Process 50 events at once for efficiency
- WebSocket throttling: Throttled live updates to prevent client overload
Technical Achievements
Implemented in-memory LRU cache that dramatically improves query performance for frequently accessed data. Careful cache invalidation ensures data stays fresh while maximizing hit rates.
Batch processing and WebSocket throttling keep the system responsive even under heavy load.
