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

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

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);

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

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

const result = await stream.request('POST', '/transform',  data: payload ,  timeout: 5000 );
