Analysts must count 311-style social alerts in sliding five-minute windows as messages arrive. Which streaming analytics pattern is this?
Select an answer to reveal the explanation.
Short Explanation
Five-minute sliding counts on live 311-style alerts are windowed aggregation—tally what showed up in each moving time box. A once-a-year total or a frozen PDF is not that pattern.
Full Explanation
Windowed aggregations compute metrics over time windows on continuous streams, such as five-minute sliding counts of alerts. Yearly one-shot totals, schema-registry deletion as a metric, and never-refreshing PDFs do not illustrate streaming windowing.
