-----------------------------------
[~hxd] Hi. I think the problem is not indicated clearly. It's not we cannot
deduplicate paths here, but we have no necessary to do it. When execute 'group
by device' query, we generate deduplicated paths from deduplicated measures for
device every time. So the work we need to do is to dedupliacte measures. The
paths is no acutal meaning and only for timeseires validation here.
> Paths are not correctly deduplicated
