A revised window representation is generated that includes an alternative set of connections between windows in the window set based at least on an execution cost for at least one window. The revised window representation is selected to obtain the data result for each of the plurality of original time windows. A revised query plan based on the revised window representation is provided to obtain the data result for each of the plurality of original time windows.
