Abstract
The capabilities of individual nodes that process a query may be evaluated to perform query planning. An operation of a plan to perform a query can be identified for assignment to a node based on the capabilities of nodes to perform the query operation. A node may be selected based on the difference between the selected node's capability to perform the query operation and other nodes capabilities to perform the operation. Capability-based selection can be performed at runtime, in some embodiments, in order to make query operation assignments based on further information obtained as a result of performing prior operations in the query.
