Technical Details

Session Management: Each visitor gets a temporary session ID (5-minute TTL) to track page visits and activity without persistent identification.

Data Structure: Sessions stored as ["live_sessions", sessionId]with atomic counters at ["live_count", "total"] for consistency.

Trend Analysis: Activity aggregated in 5-minute buckets at ["live_trend", timestamp] for historical insights.

Scalability: Distributed KV storage with edge caching enables global deployment while maintaining real-time performance.
