Hello all,

I am looking for a suggestion.

I have a series GPS of various other cars(different ID) stored in Cassandra table which stores it in ascending order of time w.r.t id of particular car (i.e the kind of which we get by group by ID sorted in ascending order of time) and I want to use window function and partition by on the basis of car ID and order by on the basis of GPS time. I am trying to understand the need for order by using window with partition by on already ordered and what`s the necessity to use the same on this particular use case .

Any sort help is appreciated !
