Consistency / Latency
Kind: tension
Record: tension:consistency-latency
Canonical: Schema
"consistency" (atomic-boundary layer) is traded against "Latency" (performance-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Latency" and choosing an explicit operating point.
Listed in Tensions, after Consistency / Availability and before Isolation / Throughput.
