Client

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

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

stream.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);

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

Client

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 );

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