Hi,
Though there is no a particular command for this feature, we have some
alternative features:
- SELECT INFO: select the data (usually it is an aggregation query)
and write the data into another time series;
- Continuous Query: run a query at a fixed time interval and save the
data into another time series.
see [1] and [2]
