Pessimistic Locking / Lock-Free Throughput
Kind: tension
Record: tension:lock-free-throughput-pessimistic-locking
Canonical: Schema
"pessimistic-locking" (atomic-boundary layer) is traded against "Lock-Free Throughput" (atomic-boundary layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Lock-Free Throughput" and choosing an explicit operating point.
