摘要: Techniques for performing dynamic load balancing during distributed query processing are provided. In one embodiment, a first node in plurality of nodes can execute an instance operator, where the operator is part plan database that processed manner by nodes. The further monitor its level while executing occurs. If exceeds threshold, split amount remaining work associated with into portion and second portion, determine state information moving execution from to node, save data store.
