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

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

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

Changelog

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

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.
