┌─────────────────────────────────────────────────────────────────────────────┐
│ WIDE EVENTS ARCHITECTURE │

│ Traditional Wide Events │

│ logger.info("Fetching cart") user: { id, tier, account_age }, │
│ logger.debug("Cart items: 3") cart: { id, items, total }, │
│ logger.error("Payment failed") payment: { method, latency_ms }, │
│ outcome, error │
│ → 5 logs, hard to correlate }; │
│ → Requires string searching logger.info(event); │
│ │
│ → 1 event, fully queryable │
│ → High cardinality = fast debugging │
