A tumbling windows assigner assigns each element to a window of a
specified window size. Tumbling windows have a fixed size and
do not overlap. For example, if you specify a tumbling window
with a size of 5 minutes, the current window will be evaluated
and a new window will be started every five minutes
as illustrated by the following figure.
