Which term refers to a data stream control that limits and restricts full data volume by updating less frequently?

• A. VWAP
• B. Conflated
• C. Update rate
• D. Redundancy

Answer: (B)

Conflation is the data stream technique that limits the full data volume by delivering updates less frequently. It works by combining multiple rapid updates into a single message within a set interval, usually keeping only the latest value for that interval. For example, a feed that would normally push every price tick can be configured to send just one update per second, representing the most current price. This reduces bandwidth while still providing timely information. VWAP is a calculated benchmark, not a streaming control. Redundancy refers to duplicate or extra data, not the mechanism of reducing update frequency. Update rate is the frequency parameter itself, but the concrete method described is conflation.
