Window Loop Start

The Window Loop Start node takes a table as input and defines a window of a certain size. In each iteration a chunk of rows of the input table is returned and the window is moved by a defined step size until the end of the table is reached. The returned chunks contain rows, which lie within the window of the specific iteration. The size of the window is defined in terms of either the number of rows it contains or the date/time interval it covers.
