Swift and quotas in upcoming 1.8.0 (Grizzly) release.

There is two new nifty middlewares for doing quotas in upcoming Swift release 1.8.0 called container_quotas and account_quotas.

Those are two different middlewares because they are actually addressing different use cases.

container_quotas is typically used by end users the use case here is to let user to specify a limit on one of their container.

Why would you want to restrict yourself you may ask ? This is because when you allow a public upload to a container for example with tempurl or/and formpost you want to make sure people are not uploading a unlimited amount of datas.

The headers to configure for the container quota are :

X-Container-Meta-Quota-Bytes – The Maximum size of the container, in bytes.
X-Container-Meta-Quota-Count – Maximum object count of the

The account_quotas is more the typical quota implementation. A “super
user” with the reselleradmin group/role can set a byte limit for
an account and the account will not be able to have new
objects/containers until someone cleanups his account to get under the
limited quotas.

The headers to configure the account quotas are :

X-Account-Meta-Quota-Bytes – The Maximum size of the account in bytes.
