- Design comprehensive rate limiting for both reads (REQ) and writes (EVENT)
- Implement PID controller with filtered derivative to avoid noise amplification
- Apply low-pass filter before derivative computation (bandpass effect)
- Add anti-windup for integral term to prevent saturation
- Support setpoint-based control (target operating point as memory fraction)
- Separate tuning parameters for read vs write operations
- Monitor database-specific metrics (Badger LSM, Neo4j transactions)
- Combine memory pressure (70%) and load level (30%) into process variable
- Include integration examples for WebSocket handlers and import loop
- Add configuration via environment variables with sensible defaults
