receiving a request to replicate a dataset of a database that is stored in a cloud-based data warehouse at a first region of a plurality of geographic regions to a second region of the plurality of geographic regions, wherein the second region is subject to persistent storage restrictions different from restrictions of the first region;
selecting a replication policy, applicable to the second region, wherein the replication policy specifies replication restrictions that conform to the persistent storage restrictions of the second region, wherein the replication restrictions specify a format of storage in which the dataset is permitted to be stored at the second region, and wherein the format of storage is one of volatile storage and non-volatile storage; and
replicating the dataset from the first region to the second region, including applying the replication restrictions of the replication policy to the dataset.
