Why This Topology Works
Flags are evaluated server-side for consistency, cached in Redis for sub-millisecond reads. PostgreSQL provides the audit trail. Analytics closes the loop on A/B test outcomes.
Scaling Notes
Redis cache means flag evaluation doesn't hit the database. Analytics writes are batched and async. The flag service is stateless and horizontally scalable.
Observability
Track flag evaluation latency, cache hit ratio, and A/B test statistical significance. Alert on unexpected flag state changes.
