Window function requires a timestamp column because you will apply a
function for each window (like an aggregation). You still can use UDF for
customized tasks

Hi:I would like to use window function on a DataSet stream (Spark 2.2.0)The
window function requires Column as argument and can be used with DataFrames by
passing the column. Is there any analogous window function or pointers to how
window function can be used for DataSets ?
Thanks
