Transient traffic incidents should disappear from a hot operational store after a set period without manual cleanup jobs. Which NoSQL operational feature fits this need?
Select an answer to reveal the explanation.
Short Explanation
Old fender-bender alerts should fade out on their own—that is TTL. Set an expiration and the hot store cleans itself. No nightly clerk with a delete key required.
Full Explanation
Time-to-live (TTL) features expire records automatically after a configured duration. Transient traffic incidents belong in hot operational stores only while relevant, then should leave without manual cleanup. Permanent retention of every incident in the hot tier wastes capacity and muddies current views. TTL is a practical NoSQL operational pattern for short-lived civic events.
