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

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' );

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

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

const throttled = stream.throttle( rps: 100, burst: 200 ); const deduplicated = stream.dedup( key: 'event.id', window: 60000 );
