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

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.

const batch = stream.pipe(filter((e) => e.type === 'payment'), batch(100), debounce(5000));
