Abstract: The cloud data platform receives a first query directed towards a shared dataset, the first query identifying a first operation. The platform accesses a first set of data from the shared dataset to perform the first operation, the first set of data including data accessed from a first table of the shared dataset. The cloud data platform determines that an aggregation constraint policy is attached to the first table, the aggregation constraint policy restricts output of data values stored in the first table and enforces the aggregation constraint policy on the first query based on a context of the first query. The cloud data platform generates an output to the first query based on the first set of data and the first operation, based on enforcing the aggregation constraint policy on the first query.
