Explanation
Unlike tumbling windows, hopping windows model scheduled overlapping windows. A hopping window specification consist of three parameters: the timeunit, the windowsize (how long each window lasts) and the hopsize (by how much each window moves forward relative to the previous one). Additionally, offsetsize may be used as an optional fourth parameter. Note that a tumbling window is simply a hopping window whose ‘hop’ is equal to its ‘size’.
