Architects describe a nightly batch correction path alongside a speed layer that feeds live operational metrics. What architectural idea are they applying?
Select an answer to reveal the explanation.
Short Explanation
Nightly cleanup and live gauges can share the stage. Keep the batch path for hard corrections and the speed path for right-now metrics — do not fire one because the other exists.
Full Explanation
Lambda-style architectural awareness (without requiring jargon fetish) means batch and speed paths coexist: batch recomputes authoritative views while speed serves low-latency metrics. Civic ops often need both correction quality and live visibility. Removing either path unilaterally, or reverting to whiteboard tallies, discards that balance. Serving layers then merge or present views appropriate to each consumer.
