Abstract
Facilitating flexible windows in querying continuous data streams. In one embodiment, a software code is associated with a window, wherein execution of the software code determines the values to be included in the window. On receiving a query indicating the window, the result of the query is generated based on the values in the window determined by execution of the software code. The software code may be identified by an identifier and thus used for different queries on the same or different continuous data streams.
