Stepping stone to simplifying
dvc fetch/pull
by using index.Fetch handles regular imports through index already, but not repo imports because their processing is much more involved (e.g. chained imports) in the current arch.
With
FileStorage
support introduced intoDataIndex
anddatafs
supporting imports overall,dvcfs
can now handle repo imports (even chained ones). This will soon allow us to handle repo imports the same way we handle regular ones, improve performance and get rid of a lot of messy code (e.g. DependencyRepo).Related iterative/scmrepo#207
