Streaming

Error handling is explicit: catch failures at any stage, log them, and route bad events to a dead-letter queue without stopping the main pipeline.

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

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

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

Streaming

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 );

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