Design a live events pipeline for a product emitting clickstream/telemetry: ingest events off a streaming bus, process them in flight, land raw then curated data in a layered lake, and serve both a real-time index and ad-hoc analytics — at sub-minute freshness, with a reprocessable raw history in S3.
This is the one scenario where the deadline is short enough to change the shape of the pipeline.

Run the review to check your architecture against this scenario — a valid DAG, a trigger for the freshness SLA, a transform stage, a quality gate before publish, and a failure path — then defend it in a short interview.
This scenario runs a full workspace — editor, canvas and results side by side. It needs a laptop or desktop to be usable. Open this page on a bigger screen to start building.
