Finally, we subtract each timestamp + 1 month from itself. It's worth noting that subtracting two timestamps will always produce an interval in terms of days (or portions of a day). You won't just get an answer in terms of months or years, because the length of those time periods ...
The next frame unit,range, does not count rows at all. Instead it uses the value of the sort key (order byexpression) and adds or subtracts the specified<distance>. All rows for which the value of the sort key falls into the specified range are taken into the frame. Note thatcurrent ...

This is accomplished in SQL using the LAG window function, which subtracts each row from the previous row ordered by the created column. Cluster performance over time This first example queries the "snapshots" table, which stores the aggregate total of all statistics for the entire cluster. Runn...
