'dvc get' is cloning the full bitbucket repo when only one branch is needed

[anjapago]

DVC version : 0.82.2

When using dvc get to get data from a large bitbucket repository (with full command dvc get --rev branchname https://.../gitrepo data/data.csv), this results in cloning the full git repository, even though only the one specified branch was needed. It would be preferable to be able to only clone the one specified branch.

hi, @anjapago , could you try to see if this quick and dirty workaround helps:

pip install git+https://github.com/shcheklein/dvc@workaround-3473

(use it this way dvc get --rev=feb20gem https://github.com/iterative/blog yarn.lock - always specify --rev)

More context from the discussion. Full clone takes ~20min which makes commands like dvc get, dvc list, dvc import as well as dvc.api effectively unusable.

Right. Ping myself :)
