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

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

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

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.
