Re: [jira] [Commented] (IOTDB-1141) Down-sampling storage

[Xiangdong Huang <sa...@gmail.com>]

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]

Best,

> > Currently, the IOTDB does not support down-sampling storage, whereas the InfluxDB supports down-sampling storage. For example, data generated one month ago is reduced from seconds to hours, and data generated one year ago is reduced to days.
