Abstract
The present disclosure extends to maintaining an item inventory status at an inventory cache management system. The inventory cache may be refreshed regularly by a threshold-based triggering mechanism. In embodiments, as item inventory breaches certain thresholds, the inventory cache may be refreshed with increased frequency to mitigate overselling or underselling scenarios and reduce overall network traffic for items having relatively high inventory levels.

- at the primary inventory cache, storing a first inventory status corresponding to the first item inventory level quantity;
- at the parallel inventory cache, storing the first inventory status;
- at the parallel inventory cache, storing a second inventory status corresponding to a second item inventory level quantity, the second item inventory level quantity is different than the first item inventory level quantity and the second item inventory level quantity comprises a quantity of an item available only after a selected starting date and time;
