Graceful shutdown waits for in-flight events to complete, then closes connections cleanly—no lost events, no crashes.

stream.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.
