REAL-TIME SECURITY MODEL PROVIDING INTERMEDIATE QUERY RESULTS TO A USER IN A FEDERATED DATA SYSTEM

摘要

The subject technology provides configurations for receiving a query for data stored across data systems in which the query is associated with a user. It is determined if the user has permission to execute an operation from the query at a data in which the operation is executed upon at least one table provided by the data system. The subject technology determines if the operation corresponds to a cache object in a cache registry if the user has permission. Each cache object is owned by a cache manager user. A view associated with the user is created that provides temporary access privileges to the cache object corresponding to the operation in which the cache object includes results of the operation executed in the query and the cache object is owned by the cache manager user. The results of the operation are then provided in the created view to the user.
