Time series aggregate functions perform computations on a set of time series data, allowing users to extract meaning from vast quantities of sensor data. These functions use the GROUP BY TIME clause to present the results in terms of time. Time series functions are either traditional functions that can be used with a GROUP BY TIME clause or functions that operate only on time series data.
For more information on using the GROUP BY TIME clause, see Time Series Aggregates and SELECT Extensions. For more information on time series aggregate functions, see Time Series Aggregate Functions.
