A traffic-management center needs curb-lane occupancy updates every few seconds rather than overnight batches. Which of the 4 V's does this requirement primarily stress?
Select an answer to reveal the explanation.
Short Explanation
Overnight batch is a slow river; curb occupancy every few seconds is a fire hose. That timing demand is Velocity—how fast the data shows up and has to be usable. Bulk archives or rumor fights are different headaches.
Full Explanation
Velocity characterizes high-speed data arrival and processing needs. Requiring curb-lane occupancy every few seconds rather than overnight batches is a velocity-driven requirement. Volume concerns scale of storage, variety concerns heterogeneous formats, and veracity concerns trustworthiness; those are not the primary constraint described in the traffic center's need.
