When querying in Apache IoTDB Version 0.13.3, why results are duplicated for crertain timestamp ranges?


My Apache IoTDB version is 0.13.3. Why are there duplicate data timestamps and values when querying data? The query statement I used is select X1 from root.ops.K01 order by time desc. The result of X1 should be either true or false, and the results are consistently repeated within specific timestamps (the duplicates are continuous). I need to determine whether this issue is related to the data type I have stored or the query statement I have used, and how to address it.


Solution

  • This may be a old version bug of Apache IoTDB. Since Version 0.13.3 is no longer maintained, and the order by time desc has bug that has been fixed in the newer version, it is recommended to upgrade to newer version (recommended you to upgrade to version 1.3).
