Abstract
Certain example embodiments provide efficient policy-based access to data stored in memory tiers, including volatile local in-process (L1) cache memory of an application and at least one managed (e.g., non-volatile) in-memory (L2) cache. Operations include receiving an access request for access to a data element in L2; detecting whether a copy of the data element is in L1; if so, copying the data element and the access policy from L2 to L1 and providing the user with access to the copy of data element from L1 if the access policy allows access to the user; and if not, determining, by referring to a copy of the access policy stored in L1, whether the user is allowed to access the data element, and, if the user is allowed to access the data element, providing the user with access to the copy of the data element from the L1 cache memory.
