Streaming

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

Each event flows through a series of transformation stages, with built-in support for filtering, mapping, and conditional routing.

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

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

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

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