Hello, I would like to know how tags and branches are "cheap copy" in terms of time and space.
Since we can't reorganize the layout, we will need to tag big directories (about 500 Mb) even if we just sparse-chechkout single files. This operation might be done up to 10 times per day. Is this operation really a constant-time copy? What about space? (We can't try by ourselves yet, we are extimating on the experience of the community on big projects) Thanks.
