Norway


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 (i.e the kind of data 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 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 data and what`s the necessity to use the same on this particular use case .

Any sort help is appreciated !
