in the 2.0, I can see the datafile composed of three files which are .data file,.last,.head file.
By the time of 3.0 version. it is changed to data, stt, head, sma file.
what is the difference between TDengine 3.0 datafile and 2.0 datafile?
In TDengine 3.0 version , there is no .smal file anymore but only .sma file . it is the equivalent of .smad file in 2.0 version
the .data file in TDengine 3.0 version is the partly same thing with .data file in 2.0 . except for multi-version introduced.
the .head file in TDengine 3.0 version is the total same thing with .head file in 2.0 .
.stt file in TDengine 3.0 version is the functionally same thing with .last file in 2.0 .
