Abstract
A TTL value for a data object stored in-memory in a data grid is dynamically adjusted. A stale data tolerance policy is set. Low toleration for staleness would mean that eviction is certain, no matter the cost, and high toleration would mean that the TTL value would be set based on total cost. Metrics to report a cost to re-create and re-store the data object are calculated, and the TTL value is adjusted based on calculated metrics. Further factors, such as, cleanup time to evict data from a storage site, may be considered in the total cost.
