> Currently, the tagIndex in metadata module uses mlog to recover.
> However, if user alters one timeseries' tag, the tag will only be updated to the tagLogFile rather than mlog.
> Thus, after tag update operation, the recover won't use the up-to-date tag information in tagLogFile but use the outdated tag information in mlog.
