> Why when find_version is false, the rowset is unuseful?
I think you want to ask why when find_version is **true**, the rowset is
unuseful. Because when version founded, means the tablet has the data in this
version (maybe compacted), we can sweep up this rowset. Only when the rowset
has some new data (version is not covered, i.e. find_version is false), the
rowset is useful.
