Changelog

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

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

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

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

Changelog

Authentication tokens are rotated silently in the background; your code never handles credentials directly.

await stream.on('user.created', async (event) =>  console.log(event.data.email); );

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