It's hard to tell what his intentions were, but certainly questions are needed such as:
- Chris December 04, 2017- multiple "directories" per user?
- multiple users per directory?
- if prefix matches, does it mean he has access to all sub. dirs.?
- can there be a revoke in a sub. Dir?
- how many grants / user typically, outliers?
- how many users, how many directories.
- how deep are those paths typically, where is the grant in this hirarchy
One approach can be, have an entity for a user, and a list of directory prefixes, load the user with grants and check if path-prefix is in there, maybe cache user. If there are thousands of grants per user but only few grants per directory, you may do the opposite on the directory, load per prefix the number of users.
