API

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

The TypeScript types are fully inferred; no manual type assertions needed even with complex nested schemas.

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

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

API

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

await stream.ack(event.id); const pipeline = stream.filter(e => e.amount > 100).map(e => ( ...e, fee: e.amount * 0.03 )).on('error', (err) => logger.error(err));

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