How does Google Maps find the attachment?
Clarify what “attachment” means, such as a user-uploaded photo, review media, business document, or place association, then design the end-to-end ML system that retrieves the most relevant attachment. Explain the data, model stages, serving path, evaluation, and failure handling. Treat scale, latency, freshness, privacy, and training-serving consistency as requirements to clarify rather than assumptions.
