This solution is going to be killed. The DB cost of maintaining the depth (triggers, functions, etc) is too high compared to making nested selects whose performance (in query terms) is worse but not by much.

Now this is the analysis given this folders structure:
Level 1 with 5000 folders
|_ Level 2 with 5000 folders
|_ Level 3 with 5000 folders
|_ Level 4 with 5000 folders
|_ Level 5 <- here's the folder to check

Update all depths (migration):

Move a subfolder into a parent (all subfolders have to be updated recursively)

Get a folder by name and depth

Get a folder by name (using nested selects and no depth)
