Abstract
A system for enforcing projection constraints on data values stored in specified variables of a shared dataset of a cloud data platform. A request is received from a first account of the cloud data platform that identifies a first operation to be performed on the shared dataset. A first set of data, including data accessed from a first variable, is accessed from the shared dataset to use in performing the first operation. A projection constraint policy attached to the first variable of the shared dataset is determined, and the projection constraint policy is further determined to be enforced based on the request. Based on the first set of data and the first operation, an output to the first request is generated.
