imay commented on issue #2195: why storage medium setting only supports the path extension? URL: https://github.com/apache/incubator-doris/issues/2195#issuecomment-554833186 > @imay How about "storage_root_path = < path >, < capacity >, < medium > "? If this format is used, if `capacity` or `medium` is not specified, what does the final path look like? like"< path >, , < medium >" or "< path >, < capacity >,". And if other property is added to this path later, the what will the format be? How about the format like "path,medium=xxx,capacity=xxx". If user don't specify medium and capacity we use the default option. > We can set medium after the capacity limit, it's optional. So we can still use "storage_root_path = /home/disk1/palo.HDD,50;/home/disk2/palo.SSD,1;/home/disk2/palo" to set root path. > I'd prefer to delete reading medium from the extension. But if you want to keep it, that's no problem. Even we support new format of path, we should be compatible with old format. Because there are already many instances running now, we should make them happy. > Who has the greater priority, extension or medium parameter?
