Custom Repository folder for each user

Hello,

I have developed a custom repository that has 1 folder for each user:

REPOSITORY

-USER1

-USER2

-.........

I want to reload the documents based on roles for example:

-Manager should see all the documents, so a full reload to the structure is made.

-User1 only reloads the USER1 folder...

Should i achieve this using refresh times? Or make the reload dependent of the current logged in user, validating and invalidating caches ?

What is the most feasible solution ?

Thanks

Best Regards,

Joã
