Overview

A storage implementation that does not persist data to any form of storage. When looking up the storage object for a domain, it’s easier to treat a missing domain with a Null storage than checking for nil.

For example, presence subscription stanzas sent to a pubsub subdomain have no storage. Rather than checking for nil storage or pubsub addresses, it’s easier to treat stanzas to pubsub domains as Null storage that never finds or saves users and their rosters.
