> Using snapshot diff command, we can generate a diff report between any two
> given snapshots under a snapshot root directory. The command today only
> accepts the path that is a snapshot root. There are many deployments where
> the snapshot root is configured at the higher level directory but the diff
> report needed is only for a specific directory under the snapshot root. In
> these cases, the diff report can be filtered for changes pertaining to the
> directory we are interested in. But when the snapshot root directory is very
> huge, the snapshot diff report generation can take minutes even if we are
> interested to know the changes only in a small directory. So, it would be
> highly performant if the diff report calculation can be limited to only the
> interesting sub-directory of the snapshot root instead of the whole snapshot
> root.
