Invalidation and refresh of multi-tier distributed caches

A system, comprising:

• a local cache manager configured to:
• connect to a data consuming application,
• wherein the data consuming application receives derived data in response to passing core data to an application program via an application programming interface;
• refresh a local cache of data comprising the core data and the derived data used by the data consuming application;
• a shared cache manager running on a caching system configured to:
• detect a changed core data instance from among the core data;
• infer impacted derived data related to the changed core data instance;
• pre-cache an updated version of the impacted derived data by replaying an application programming interface access dependent on the changed core data instance;
• inform the local cache manager about the changed core data instance and the impacted derived data;
• determine whether the impacted derived data is of continuing interest;
• and
• replay the at least one application programming interface access with the changed core data instance to refresh the impacted derived data from the application programming interface access.

A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• receiving, by a shared cache manager, information about requests from a data consuming application,
• wherein an application program running on a server accessed by the data consuming application via an application programming interface receives core data as input and returns derived data;
• detecting, by the shared cache manager, a changed core data instance from among the core data;
• inferring, by the shared cache manager, impacted derived data from the changed core data instance;
• pre-caching, by the shared cache manager, an updated version of the impacted derived data by replaying at least one application programming interface access that is dependent on the changed core data instance;
• informing, by the shared cache manager, a local cache manager of the changed core data instance and the impacted derived data;
• and
• satisfying, by the shared cache manager, the requests for the changed core data instance and the impacted derived data from a memory cache where a follow-up request can be satisfied by the shared cache manager without accessing the application program.
