| Failure Scenario | Behavior | Mitigation | |----------------|----------|-------------| | Sudden traffic spike (10x) | TTL may increase briefly due to high freq → staleness risk | Enforce TTL ceiling + min TTL floor | | Silent data corruption at origin | HeidyModel-006 caches stale data longer | Integrate with version vector or etag | | Cold start (no history) | Default to conservative TTL (e.g., 10s) | Warmup with static TTL first | | Clock skew between nodes | Inconsistent TTL decisions | Use logical timestamps (monotonic clock) |
:
HeidyModel-006 reduces origin load by ~59% with a minimal staleness increase in P95. TTL Models - HeidyModel-006
