Does anyone know that why the fill(previous) statement is not working for Version 1.0.1 of Apache IoTDB? I updated from Version 0.12, and when I tried the same statement, there is no effect and no blank value are filled. I need to filled this time series with blank values from the values docked by the previous time series. Anyone know are there any initialize operations I need to do to successfully use fill(previous)?

fill(previous) in Apache IoTDB is to fill the value according to the original result set. If you need to fill in the value from the time series before your time of null values, you can expand the time range when querying in IoTDB.
