> In current implementation of compaction, the default sort dimension is file
> version when selecting compaction tasks. It will lead to compaction error in
> tsfile load scenario. It is because the TsFile with higher version may not
> has greater timestamp when the TsFile is loaded by tools.
>
> Solution:
> change the sort dimension from file version to timestamp.
