Abstract:

A computer system including in-memory cache storage may be used to store collections of metadata that provide a semantic layer for a query of a data source. The computer system may provide multiple users access to the metadata collection, using different security policies for the users, without duplicating the metadata collection in the in-memory storage. For instance, the computer system may retrieve the metadata collection and provide the first user access to the metadata collection based on a first security policy of the first user. The computer system may then provide a second user access to the metadata collection based on a second security policy of the second user, without the metadata collection being duplicated in the in-memory cache storage.
