> When cleanfile cleans up data, it cleans up all the carbonindex and
> carbonmergeindex that once existed, even though many carbonindex have been
> all deleted, which have been merged into carbonergeindex. considering that

> completion of the compaction, the clean file command will take serveral hours.
> Here, we just need to clean up the existing files, carbonmergeindex or
> carbonindex files
