> After v2 upgrades the v3 dictionary, if v2 and v3 are mixed, the query result
> is incorrect
> Root Cause
> The project opens the v3 dictionary construction, but when the v3 dictionary
> construction reads the v2 dictionary, the db name is not included in the
> path, so the v2 dictionary will not be read, causing the v2 upgrade and the
> v3 dictionary conversion step to be skipped directly, and v3 is equivalent to
> recoding. Therefore, the v2 upgrade v3 dictionary must not be available, and
> the encoding is disordered.
