If you have a cluster at 75% utilization because the workload is fully in cache and something happens that does not allow the workload to be processed in cache

If you have a cluster at 75% utilization because the workload is fully in cache and something happens that does not allow the workload to be processed in cache and your processing speed slows by half then your cluster would immediately require twice the resources to meet the workflow demand. An attacker for example could figure out a rarely used access pattern that trashes the caches and causes a severe backup.
- BubRoss 8y agoOnce again, that would imply that someone is both hardcoding a cache size and yet somehow making their use of the cache data dependant. I'm not sure what specifically you are trying to say here. It sounds like you have some sort of fear of edge cases in general, regardless of anything that has to do with caches.
