I have a large monolithic project where the repository is currently about 1.5GB and I'm wondering if breaking it into smaller submodules and only working on the submodule would help speed up cloning time and keep the storage use the same without increasing it.
If I work on a submodule within the main repository, won't those changes be stored in the main repository and the submodule's repository effectively duplicating the changes and storage requirements?
Is this the right tool for the job, or is there another approach I can leverage to work on a small chunk whilst also having it "grouped" under 1 umbrella, so if I want to work on everything, I can easily do that.
