using cassandra as backend storage instead of filesystem

[Bron Gondwana]

Yes - Raymond and the OpenIO team are working on this at the moment.  Not
Cassandra specifically - we're looking at a filesystem backend and the OpenIO
object store first, but general enough to plus other object stores as well.

I'm also doing some work on rewriting some of the internal datastructures to
be more friendly to being stored in an external database rather than the binary
internal formats that Cyrus uses.
