I want to use the drop box instead of S3.
Dropbox is very satisfactory in its function.
But there are some problems.
There's a concurrent write limit per namespace.
If you have a folder structure like below,
Does everyone have a namespace?
Or does it only apply to subfolders?
Or is it just the top-level folders?
.
└── root (user)/
├── FirstNamespace/
│ ├── FirstFirstNamespace
│ └── FirstSencodNamespace/
│ └── FirstSecondFirstNamespace
└── SecondNamespace/
├── SecondFirstNamespace
└── SecondSecondNamespace
