Abstract
A database management system implemented in a cloud computing environment. Operational nodes are assigned as groups of controller-nodes, compute-nodes or storage-nodes. Assignments as compute-nodes or storage-nodes vary during execution of queries. Queries specify tables for an associated database operation, and respective storage nodegroup(s). The number of nodes executing a query may change by (a) changing a compute-nodegroup, or (b) adding or removing nodes from a compute nodegroup; and/or distributing data to the storage nodegroup based on a Distribution Method which may be specified by a Distribution Vector (DV) that determines at least where each row is stored.
