Reference

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

Each event flows through a series of transformation stages, with built-in support for filtering, mapping, and conditional routing.

const throttled = stream.throttle( rps: 100, burst: 200 ); const deduplicated = stream.dedup( key: 'event.id', window: 60000 );

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

Reference

The SDK provides both callback-based and Promise-based APIs, so you can use it with callbacks, async/await, or Observables.

await stream.on('user.created', async (event) =>  console.log(event.data.email); );

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