Same GitLab for multiple users with different content visibility

Question

I am currently working on a project with multiple partners with the code stored in GitLab. Although the partners share the same core code, some files (for instance, preprocessing scripts for their own data) should only be seen by the partner who owns the respective data.

Initially, I thought about making a separate repo for all of them, but this results in a great overhead of updating all repos whenever I make a change to the core code.

What is the best way to share the main code considering that:

• The users only see the core code and their respective code.
• Whenever I make changes to the core code, they all get the updates.

Thanks

Separate repositories remain the safest option in your case.

but this results in a great overhead of updating all repos whenever I make a change to the core code.

It should not, if each partners' repositories reference your own as a submodule, following a branch.

Then a git submodule update --remote should be enough to update said submodule to the latest of that branch.
