During her doctoral work, Ortega identified a fundamental limitation of conventional TTL: . Traditional TTL values are set once—often arbitrarily—without consideration for data semantics, workload patterns, or network conditions. This mismatch leads to unnecessary cache invalidations, stale reads, or, conversely, data persisting far longer than needed, increasing storage costs and attack surfaces.
