Is that possible to write a file system over Cassandra?

Hi, Cassandra has a good distributed model: decentralized, auto-partition, auto-recovery. I am evaluating about writing a file system over Cassandra (like CassFS: http://github.com/jdarcy/CassFS ), but I don't know if Cassandra is good at such use case? Regards

Re: Lucandra or some way to query

I think Lucandra is really a great idea, but since it needs order-preserving-partitioner, does that mean there may be some 'hot-spot' during searching?
