Interview Prompt
Find the boundary. The Flink job's exactly-once guarantee ends at every cross-system sink it writes to, and the four sinks on the canvas are not all equivalent. Reroute the analytics consumer's incoming connection so it reads from a sink whose cross-system boundary is end-to-end idempotent in the scenario as labeled, without further configuration the canvas has not granted.
