Description

We should use some kind of autoscalling for storing nodes to get a better performance with thousands of users. Currently we store for example the subscriptions like:

/subscriptions/username/mailboxname

With autoscalling it would look like this:

/subscriptions/u/us/use/user/..../m/ma/mai/mail/...

See this for some ideas:
