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

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

const client = new queryhub.Client( auth: 'Bearer token', retry: true, timeout: 30000 );

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

Changelog

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.

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

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