URL: https://github.com/apache/iotdb/issues/11791
In IoTDB, there are time series under root.device_id, where xxxx represents multiple series. I would like to query for the last changed value and the time of change under root.device_id. How should I write the query statement?
such as :1,2,2,3,3,3,3,3,3，i need find when data change from 2 to 3
