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

const stream = new RelayKit( apiKey: process.env.API_KEY, region: 'us-east-1' );
