Day 9 Check Streaming and Big Data

Check yourself

Ten questions on the two designs from Day 9, the click aggregator and live chat. Both deliberately throw data away, and both run a fast approximate path alongside a slower complete one. Several questions ask you to say exactly where each one loses data and why that is acceptable.

You will be asked 10 questions drawn from a larger bank, so a second attempt will not be the same paper. Answer from what the designs actually said, not from what sounds sensible in general.
