A recently granted patent (Publication Number: US11880572B2) discloses a method for refreshing data in cache memory efficiently. The method involves setting a refresh indicator to "true," refreshing the data in the cache memory when the indicator is true, and then setting the indicator back to "false" after the refresh. The indicator remains true during non-working days and resets to false before the first working day after a break. The system ensures that data is refreshed at optimal times to prevent staleness and is designed to handle bulk job processes effectively.

Furthermore, the patent includes details about a computer program product and a system implementing the method. The program product sets the refresh indicator upon user login, refreshes data during non-peak resource usage, and resets the indicator post-refresh. It accounts for holidays, ensuring the indicator remains true throughout the break and resets appropriately. The system comprises a processor, memory, and storage media with program instructions to manage cache data efficiently. It reads stale data, refreshes it from a remote storage system, and performs bulk refresh processes based on the refresh indicator status. Overall, the patent aims to optimize data refreshing in cache memory systems, ensuring data accuracy and availability while minimizing resource usage.
