Visa International Service Association Assigned Patent

Visa International Service Association, San Francisco, CA, has been assigned a patent (12019551) developed by Gu; Yu, and Song; Hongqin, Austin, TX, for “techniques for multi-tiered data storage in multi-tenant caching systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments of the invention are directed to systems and methods for utilizing a multi-tiered caching architecture in a multi-tenant caching system. A portion of the in-memory cache may be allocated as dedicated shares (e.g., dedicated allocations) that are each dedicated to a particular tenant, while another portion of the in-memory cache (e.g., a shared allocation) can be shared by all tenants in the system. When a threshold period of time has elapsed since data stored in a dedicated allocation has last been accessed, the data may be migrated to the shared allocation. If data is accessed from the shared allocation, it may be migrated back to the dedicated allocation Utilizing the techniques for providing a multi-tiered approach to a multi-tenant caching system can increase performance and decrease latency with respect to conventional caching systems.”

The patent application was filed on 2019-10-04 (17/764879).
