Abstract

Dynamic scaling can be performed for a distributed database according to cluster-wide resource allocation. Performance metrics of different query processing nodes of a distributed database system are obtained and evaluated to make scaling decisions for the database system. Scaling operations can include increasing or decreasing database capacity units allocated to a query processing node according to the cluster-wide allocation or adding a new query processing node to a cluster, allocating database capacity units to the new node from the cluster-wide allocation of database capacity units.
