Abstract

Aspects of the present disclosure relate to metadata caching for extending data warehouse features to data lakes. The metadata cache may accelerate query execution by directly accessing non-managed data from a data lake rather than accessing data through a data warehouse. The metadata cache may allow filtering of non-managed data to improve the speed of retrieving data for executing queries.
