public class StreamExecWindowTableFunction
extends CommonExecWindowTableFunction
implements StreamExecNode<org.apache.flink.table.data.RowData>

Stream ExecNode which acts as a table-valued function to assign a window for each row of the input relation. The return value of the new relation includes all the original columns as well additional 3 columns named window_start, window_end, window_time to indicate the assigned window.
