ABSTRACT:
Provided is a stream data processing method that can effectively handle delay data. In the stream data processing method of processing data whose lifetime is defined by a window, an operation result excluding a delay tuple is immediately output along with an unconfirmed flag according to delay processing HBT while a midway processing result necessary for reproduction is retained along with the lifetime, and when the delay tuple arrives, a correct processing result is calculated from the delay tuple and the processing result restore tuple.
