Abstract

See full text

A method for processing an out-of-order data stream includes inserting a new data stream element into a segment list according to a timestamp of the new data stream element. It is identified whether there are missing data stream elements between segments in the segment list. The segments which have no missing data stream elements between them are merged. Values of the data stream elements are aggregated using a sliding window over out-of-order data stream elements in the merged segment.
