Real-time analytics with Redis counters, periodic PostgreSQL flush, and time-series aggregation. High-performance event tracking without database bottlenecks.
Rule-based anomaly detection for production systems with configurable thresholds, cooldown periods to prevent alert storms, and error pattern tracking for repeated failures.
Implement subscription tier-based feature gating and usage limits. Centralized tier configuration, database usage tracking, and clean APIs for checking limits.
