Metrics are published to standard formats (Prometheus, CloudWatch, DataDog) with zero configuration.

The core querydb object is a lightweight wrapper that manages the lifecycle of your event stream.

stream.on('*.created', async (event) =>  await db.insert('events', event); ,  concurrency: 50 );

The core querydb object is a lightweight wrapper that manages the lifecycle of your event stream.

Batching is automatic—control it via `batch(100)` or `batch({ size: 50, timeoutMs: 1000 })` to trade latency for throughput.

const batch = stream.pipe(filter((e) => e.type === 'payment'), batch(100), debounce(5000));

Error handling is explicit: catch failures at any stage, log them, and route bad events to a dead-letter queue without stopping the main pipeline.
