Patent abstract
Described herein are technologies pertaining to migrating state information of operators in a first continuous query plan to a second continuous query plan in an asynchronous manner, such that the first continuous query plan need not cease executing during the migrating of the state information. State information pertaining to stateful operators, such as join operators, is migrated from the first continuous query plan to the second continuous query plan by way of a transformation plan. State matching is utilized to generate the transformation plan.
