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] [1] https://iotdb.apache.org/UserGuide/Master/Advanced-Features/Select-Into.html [2] https://iotdb.apache.org/UserGuide/Master/Advanced-Features/Continuous-Query.html Best, ----------------------------------- Xiangdong Huang School of Software, Tsinghua University 黄向东 清华大学 软件学院 GaoYang (Jira) <j...@apache.org> 于2021年9月1日周三 上午11:17写道： > > > [ > https://issues.apache.org/jira/browse/IOTDB-1141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17407783#comment-17407783 > ] > > GaoYang commented on IOTDB-1141: > -------------------------------- > > Hi, I'm very interested in this feature and about when will it be available? > > > Down-sampling storage > > --------------------- > > > > Key: IOTDB-1141 > > URL: https://issues.apache.org/jira/browse/IOTDB-1141 > > Project: Apache IoTDB > > Issue Type: New Feature > > Components: Core/Engine > > Reporter: Chao Wang > > Assignee: Chao Wang > > Priority: Critical > > > > Currently, the IOTDB does not support down-sampling storage, whereas the > > InfluxDB supports down-sampling storage.
